Buildouts

test-package.cfg: A base buildout configuration for testing a single package with jenkins.

Features:

Provides a bin/test-jenkins executable which runs the test and some analysis tools on the content.
Detailed coverage report using coverage (optimized for use with the Cobertura Jenkins Plugin).
Pyflakes report (use jenkins Warnings Plugin).
Pep8 report
A check-translations script, warning if not translatable strings were used in templates and providing a translation statistic.

test-plone-X.cfg: There are various base buildouts extending the test-package.cfg config and using known version sets of plone for pinning the packages.

Example usage: add a configuration file to your package (test-plone-4.1.x.cfg):

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/test-plone-4.1.x.cfg

package-name = my.package

The buildout assumes that your source code is in the subfolder my/package (see option ${buildout:package-directory}) and that the package has a extras_require with the name tests (see option ${buildout:test-egg}).

plone-development.cfg: Provides a buildout base configuration for developing a plone add-on package. It is an extension for a version specific test buildout.

Features:

bin/instance : A zope instance with plone, your package and development tools installed.
bin/test : A test runner, testing this package only.
bin/test-coverage : A test runner generating and open a coverage report.
bin/zopepy : A python shell with zope environment.
omelette
bin/i18n-build: Extract and sync translation strings. All you need to keep the package's translations in sync. Also syncs the files ${buildout:package-name}-manual.pot (manually created translations) and ${buildout:package-name}-content.pot (translations from ftw.inflator initial content).
bin/upgrade: ftw.upgrade script for managing upgrade steps.

Example usage: add a configuration file to your package (development.cfg):

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/test-plone-4.2.x.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/plone-development.cfg

package-name = my.package

Buildout options

${buildout:package-name} -- The name of the package (mandatory).
${buildout:test-egg} -- Egg with extra included by test runners (defaults to ${buildout:package-name} [tests]).
${buildout:package-directory} -- Option for changing the default namespace directory. This is used for packages wich have a different name than namespace. By default, for a package with name foo.bar the source is expected at foo/bar, src/foo/bar or src/foo.bar/foo/bar.

Production

The production buildouts allows to install a Plone with custom packages in a production environment with as few configurations as possible.

The production buildouts are set up with theese features:

A ZEO-Server / ZEO-Client environment
Filestorage configuration
ftw.recipe.deployment logrotate configuration and run-control scripts
Supervisor configuration with superlance (HTTPOk per instance and Memmon)
Port range sets for all ports used in this buildout
Easily configurable

Using the buildout

Extend your buildout from production.cfg. This will install a ZEO enviroment two ZEO clients:

bin/instance0 - this is the administrative instance for maintenance. Supervisor does not start this instance automatically.
bin/instance1 - this is the productive instance where the visitors should land.

The amount of instance can be changed by extending another buildout configuration where the name of the configuration is the amount of zeo clients to install.

An example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/zeoclients/4.cfg

deployment-number = 05

filestorage-parts =
    www.mywebsite.com

instance-eggs +=
    mywebsite

[versions]
zc.buildout = ${proposed-versions:zc.buildout}
setuptools = ${proposed-versions:setuptools}

Pinning setuptools and buildout

Since the Plone KGS are pinning setuptools and zc.buildout to the version from the time of the release, it will get outdated over time. In order to use the newest versions of setuptools and zc.buildout, production.cfg provides new pinnings. It can be used like this:

[versions]
zc.buildout = ${proposed-versions:zc.buildout}
setuptools = ${proposed-versions:setuptools}

Additional ZCML

There is a problem with extending the zcml-additional. As a workaround we use the buildout:zcml-additional-fragments variable, which takes care that zcml-additional is wrapped properly.

Usage example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg

deployment-number = 05

zcml-additional-fragments +=
    <include package="my.package" file="meta.zcml" />
    <myPackageSecurity token="123123" />

Port range configuration

At 4teamwork we use a port range of 100 ports for each deployment. We use the deployment number (two-digit) as prefix and append a leading 1.

For example if we use deployment-number = 05 the ports would be:

Port	Service	Description
10500	bin/instance0	Maintenance ZEO client
10501	bin/instance1	Default ZEO client
10502	bin/instance2	Additional ZEO client (optional)
10503	bin/instance3	Additional ZEO client (optional)
10504	bin/instance4	Additional ZEO client (optional)
10505	bin/instance5	Additional ZEO client (optional)
10510	bin/instancepub	Additional ZEO client for ftw.publisher (optional)
10519	bin/maintenance	Maintenance HTTP Server (ftw.maintenanceserver)
...	bin/instance...	...
10520	bin/zeo	ZEO Server (Database)
10521	bin/zeo	ZRS Replication Port
10530	bin/solr-instance	Solr instance
10532	bin/tika-server	Tika JAXRS Server
10533	bin/redis	Redis instance
10534	gever-ui	Frontend for Gever deployments
10550	bin/haproxy	Haproxy (reserved, not installation yet)
10581	Monitor for instance1	ftw.monitor TCP socket for health checks
...	Monitor for instance...	...
10599	bin/supervisord	Supervisor daemon
8800	HaProxy	HaProxy status page (Server-wide)
8801	HaProxy	HaProxy stats socket (Server-wide)

Buildout configuration

There is a variety of options which can be configured in the buildout. Here is a full example, below is the detail explanation:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/zeoclients/4.cfg

deployment-number = 05

filestorage-parts =
    www.mywebsite.com

instance-eggs +=
    mywebsite

supervisor-client-startsecs = 60
supervisor-email = zope@localhost
supervisor-memmon-size = 1200MB
supervisor-memmon-options = -a ${buildout:supervisor-memmon-size} -m ${buildout:supervisor-email}
supervisor-httpok-timeout = 40
supervisor-httpok-options = -t ${buildout:supervisor-httpok-timeout} -m ${buildout:supervisor-email}
supervisor-httpok-view =

os-user = zope

plone-languages = en de fr

zcml-additional-fragments +=
    <include package="my.package" file="meta.zcml" />
    <myPackageSecurity token="123123" />

[instance4]
supervisor-autostart = false

These are the most common configuration settings. You can also override any options in the sections of the parts.

Details:

deployment-number - The deployment number is used as port base. See the Port range configuration section.
filestorage-parts - Configures ZODB mount points, one per line.
instance-eggs - List the eggs you want to install in the ZEO client. The Plone egg is added to this list.
supervisor-client-startsecs - The time in seconds it takes to start the ZEO client until Plone is ready to handle requests. This depends on your server and how big your database is. If it is too low, HttpOk will loop-restart the zeo clients when you restart all zeo clients at the same time and the server has load.
supervisor-email - The email address to notification messages of httpok and memmon are sent.
supervisor-memmon-size - The size of RAM each ZEO client can use. If it uses more, memmon will restart it.
supervisor-memmon-options - Allows to change or extend the memmon configuration options.
supervisor-httpok-timeout - The number of seconds that httpok should wait for a response to the HTTP request before timing out.
supervisor-httpok-options - Allows to change or extend the httpok settings per instance. The process name and the http address are added per ZEO client.
supervisor-httpok-view - Allows to specify a view name (or any path relative to the Zope application root) that will be appended to the base URL for the instance, in order to build the full health check URL for the HttpOk plugin. Must return 200 OK to indicate the instance is healthy.
os-user - The operating system user is used by supervisor, which makes sure that the processes managed by supervisor are started with this user. It defaults to zope.
plone-languages - The short names of the languages which are loaded by Zope.
zcml-additional-fragments - Define additional zcml to load. See the Additional ZCML section.
instance-zcml - Add packages to the instances zcml list.
instance-early-zcml - Add packages on top of the instances zcml list.
supervisor-autostart - by default, all instances except instance0 will be automatically started in supervisor. By setting supervisor-autostart to false for a specific [instanceX] section, this can be overridden.

HAProxy / Supervisor integration

The supervisor-haproxy event listener tells haproxy to remove backends / add backends to the load balancing when supervisor detects instances to be stopping and starting.

Example configuration:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/zeoclients/3.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/haproxy.cfg

deployment-number = 05

# If you want to change the default configuration, copy and change the settings below:
# supervisor-haproxy-backend = plone${buildout:deployment-number}
# supervisor-haproxy-socket = tcp://localhost:8801

The haproxy.cfg works well when using names in HAProxy such as "plone05" for the backend and "plone0502" for the servers (=zope instances). If you name backends and servers differently you may want to configure the name with supervisor-haproxy-backend variable.

Example HaProxy configuration:

global
   stats socket ipv4@0.0.0.0:8801 level admin

defaults
    mode http
    timeout connect 10s
    timeout client 5m
    timeout server 5m


frontend plone04
    bind *:10450
    default_backend plone04

backend plone04
    server plone0401 localhost:10401 cookie p01 check inter 10s downinter 15s maxconn 5 rise 1 slowstart 60s
    server plone0402 localhost:10402 cookie p02 check inter 10s downinter 15s maxconn 5 rise 1 slowstart 60s
    server plone0403 localhost:10403 cookie p03 check inter 10s downinter 15s maxconn 5 rise 1 slowstart 60s

Maintenance HTTP Server

When including the maintenance-server.cfg, a maintenance HTTP server is automatically configured (using ftw.maintenanceserver), listening on port 1XX19 and serving the ${buildout:directory}/maintenance directory, which is expected to contain an index.html file.

Example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/maintenance-server.cfg

deployment-number = 05

Relstorage

When including production-relstorage.cfg as the example shows below, no ZEO Server and filestorage will be installed. Besides that, the relstorage will be configured according to the relstorage buildout variables. The Following variables have to be defined in the buildout section:

relstorage-type
relstorage-user
relstorage-pw
relstorage-shared-blob-dir
relstorage-commit-lock-id
relstorage-blob-cache-size

Example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production-relstorage.cfg

relstorage-type = oracle
relstorage-user = user1
relstorage-pw = secure
relstorage-blob-cache-size = 1gb
relstorage-shared-blob-dir = false
relstorage-commit-lock-id = 7

ZODB Replicated Storage (ZRS)

Including zrs-primary.cfg configures the ZEO server as primary storage listening on port 1XX21.

Example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/zrs-primary.cfg

deployment-number = 05

Including zrs-secondary.cfg configures the ZEO server as a secondary storage replicating from the storage given in the option zrs-replicate-from in the buildout part. In addition ZEO clients are configured as read-only.

Example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/zrs-secondary.cfg

deployment-number = 05
zrs-replicate-from = primaryhost.net:10121

Tika server

The tika-jaxrs-server.cfg installs and configures ftw.tika, and sets up an Apache Tika JAXRS server as daemon, which provides document to text transforms (e.g. for fulltext indexing). A bin/tika-server script is installed and hooked up with supervisor and ftw.tika is configured. You just need to install ftw.tika in portal_setup.

Example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/tika-jaxrs-server.cfg

deployment-number = 05

Server-wide tika deployment

When having multiple Plone installations on the same server, it is effient to only use one tika server:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/tika-jaxrs-standalone.cfg
    versions.cfg

deployment-number = 99

This sets up a complete standalone deployment with a supervisor and a memmon. In order to use that in the Plone deployments, just extend the "remote" config:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/tika-jaxrs-remote.cfg

deployment-number = 05
tika-deployment-number = 99

Solr

The solr configurations provide a standard way to install solr, based on collective.solr and ftw.solr.

Standard installation

For production:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/solr.cfg

deployment-number = 05

For local development:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/plone-development.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/plone-development-solr.cfg

Custom core configuration

It is possible to change the solr core configuration or add additional cores. Take a look at the solr-core-template section in the solr-base.cfg for the options you may change.

For having the changes both, in production and development, the standard way to do customizations is to add a solr.cfg in your project repository and extend it both in development and in production buildout configurations. The solr.cfg is a configuration extension and should not extend anything.

Example local solr.cfg:

[solr-settings]
solr-cores =
    main-core
    another-core
solr-default-core = main-core

[main-core]
<= solr-core-template
max-num-results = 2000

[anothre-core]
<= solr-core-template
max-num-results = 500

Example production-*.cfg:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/solr.cfg
    solr.cfg

deployment-number = 05

Example development.cfg:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/plone-development.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/plone-development-solr.cfg
    solr.cfg

Redis

In the redis folder there are standard buildouts for installing a dedicated redis installation within the buildout directory. You can simply extend redis/development.cfg or redis/production.cfg, depending on your base config file, and then choose the redis version with e.g. redis/3.2.3.cfg.

Production buildout example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/redis/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/redis/3.2.3.cfg

Local development buildout example:

[buildout]
extends =
    test-plone-4.3.7.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/plone-development.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/redis/development.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/redis/3.2.3.cfg

collective.taskqueue

When using collective.taskqueue, you need to configure a queue and a queue-server in your buildout. For convenience there are some standard queue configuration buildouts which simply can be exended.

Local volatile queue

The local volatile queue is an in-memory queue which will be lost when terminating a process. If you do important stuff you should consider installing redis.

For production:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/taskqueue/volatile-production.cfg

For development:

[buildout]
extends =
    test-plone-4.3.x.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/plone-development.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/taskqueue/volatile-development.cfg

Redis queue

Redis can be used as queue backend. By default, redis is not configured to really persist everything. With the standard configuration provided in ftw-buildouts, redis is set up and configured to persist the queue.

For production:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/redis/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/redis/3.2.3.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/taskqueue/redis-production.cfg

For development:

[buildout]
extends =
    test-plone-4.3.x.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/plone-development.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/redis/development.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/taskqueue/redis-development.cfg

Warmup

For production deployments, the warmup.cfg installs and configures collective.warmup to automatically hit the site root when an instance is started or restarted. It also requests the resources, resulting in cooked resources (JavaScript / CSS).

It works without further configuration when there is only one filestorage-part configured and the plone site has the ID platform.

Simple example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/warmup.cfg

deployment-number = 05

filestorage-parts = www.mywebsite.com
instance-eggs += mywebsite

Note

Make sure to use instance-eggs += rather than instance-eggs =, otherwise the collective.warmup will not be installed.

When booting up bin/instance1, this configuration will make a request to http://localhost:10501/www.mywebsite.com/platform.

If you have different paths you can configuration the base path manually:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/warmup.cfg

deployment-number = 05

filestorage-parts =
    www.mywebsite.com
    test.mywebsite.com
instance-eggs += mywebsite

[warmup-configuration]
base_path = www.mywebsite.com/Plone

If you want to add more urls to check, follow the instructions in the collective.warmup readme and fill in warmup-configuration options, e.g.:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/warmup.cfg

deployment-number = 05

filestorage-parts = www.mywebsite.com
instance-eggs += mywebsite

[warmup-configuration]
urls += sitemap

url-sections +=
    [sitemap]
    path = ${warmup-configuration:base_path}/sitemap
    check_exists = Sitemap

The warmup-configuration:urls and warmup-configuration:url-sections options will be included in the generated warmup configuration file.

One thread per Zope instance

For production buildouts, it may be desirable to run Zope instances with one ZServer thread per instance in order to get more predictable memory usage and load balancing.

In order to run instances with one single thread, the single-thread.cfg can be used:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/zeoclients/4.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/single-thread.cfg

This buildout must be extended after production.cfg and, if present, zeoclients/n.cfg and warmup.cfg. It will:

Set zserver-threads to 1 for each Zope instance
Include ftw.monitor
Remove the HttpOk plugins from supervisor
Remove collective.warmup (if present)

Once this buildout is used, the HAProxy health check needs to be switched to a TCP health check to the ftw.monitor port (instead of a HTTP health check to the instance port). See the corresponding section in the ftw.monitor README for an example HAProxy configuration.

Chameleon

The chameleon.cfg enables the Chameleon templating engine with our custom integration ftw.chameleon and provides default configuration for use in production and development.

If you want to run your tests with chameleon, you should add ftw.chameleon to the install_requires list in your setup.py.

Production example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/chameleon.cfg

deployment-number = 05

Development example:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/plone-development.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/chameleon.cfg

Slack

It is often useful to send notifications to a slack channel when certain things happen. For example if you run a maintenance job you may want to receive a notification when it is finished. The slacker config just installs a simple script for slacking messages.

create a Slack webhook.
update your buildout:

[buildout]
extends =
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/production.cfg
    https://raw.githubusercontent.com/4teamwork/ftw-buildouts/master/slacker.cfg

slack-webhook = https://hooks.slack.com/services/111/222/333
deployment-number = 05

send messsages:

$ ./bin/slacker -t "Hello World"
$ ./bin/slacker -t "Done" -u "migration-bot" -i ":robot:" -c "myproject-migration"
$ echo "all done" | ./bin/slacker -s
$ echo '{"text": "Important things", "icon_emoji": "monkey_face"}' | ./bin/slacker -s -r

Options:

-t "Message, may contain emojis :+1:"
-u "user name, must not be registered"
-i ":smile:"
-c "channel"
-s read stdin
-r text is raw json

Maintaining ftw-buildouts

Updating deployment version pinnings

The production.cfg provides version pinnings for the deployment related eggs, such as buildout recipes and extensions. From time to time we want to update the production version pinnings to the newest versions. In the directory production-versions-buildout there is a buildout which helps updating to the newest version.

Usage:

$ cd production-versions-buildout
$ python2.7 bootstrap.py
$ bin/buildout
$ bin/checkversions

Then manually update the [proposed-versions] in ../production.cfg according to the versions proposed by bin/checkversions.

Finally run bin/buildout again to verify the versions constraints.
