nextcloud-dev-docker-compose

Nextcloud development environment using docker-compose

⚠ DO NOT USE THIS IN PRODUCTION Various settings in this setup are considered insecure and default passwords and secrets are used all over the place

Features

• ☁ Nextcloud
• 🔒 Nginx proxy with SSL termination
• 💾 MySQL
• 💡 Redis
• 👥 LDAP with example user data
• ✉ Mailhog
• 🚀 Blackfire
• 📄 Collabora

Getting started

To get the setup running:

git clone https://github.com/juliushaertl/nextcloud-docker-dev
cd nextcloud-docker-dev
./bootstrap.sh
sudo sh -c "echo '127.0.0.1 nextcloud.local' >> /etc/hosts"
docker-compose up nextcloud proxy

Manual setup

Nextcloud Code

The Nextcloud code base needs to be available including the 3rdparty submodule. To clone it from github run:

git clone https://github.com/nextcloud/server.git
cd server
git submodule update --init
pwd

The last command prints the path to the Nextcloud server directory. Use it for setting the REPO_PATH_SERVER in the next step.

Environment variables

A .env file should be created in the repository root, to keep configuration default on the dev setup:

cp example.env .env

Replace REPO_PATH_SERVER with the path from above.

Setting the PHP version to be used

The Nextcloud instance is setup to run with PHP 7.2 by default. If you wish to use a different version of PHP, set the PHP_VERSION .env variable.

The variable supports the following values:

1. PHP 7.1: 71
2. PHP 7.2: 72
3. PHP 7.3: 73
4. PHP 7.4: 74

Starting the containers

• Start full setup: docker-compose up
• Minimum: docker-compose up proxy nextcloud (nextcloud mysql redis mailhog)

Switching to different env settings

This can be useful if you wish to run different setups besides each other:

docker-compose --env-file stable15.env up proxy nextcloud

Besides that there are also stable containers now in the main docker-compose.yml file, which makes it a bit easier to run them side by side. However the source location needs to be adjusted for this.

Running into errors

If your setup isn't working and you can not figure out the reason why, running docker-compose down -v will remove the relevant containers and volumes, allowing you to run docker-compose up again from a clean slate.

🔒 Reverse Proxy

Used for SSL termination. To setup SSL support provide a proper DOMAIN_SUFFIX environment variable and put the certificates to ./data/ssl/ named by the domain name.

You might need to add the domains to your /etc/hosts file:

127.0.0.1 nextcloud.local
127.0.0.1 collabora.local

This is assuming you have set DOMAIN_SUFFIX=.local

You can generate selfsigned certificates using:

cd data/ssl
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout  nextcloud.local.key -out nextcloud.local.crt

Use valid certificates trusted by your system

• Install mkcert https://github.com/FiloSottile/mkcert

• Go to data/ssl

• mkcert nextcloud.local

• mv nextcloud.local-key.pem nextcloud.local.key

• mv nextcloud.local.pem nextcloud.local.crt

• docker-compose restart proxy

✉ Mail

Sending/receiving mails can be tested with mailhog which is available on ports 1025 (SMTP).

To use the webui, add 127.0.0.1 mail.local to your /etc/hosts and open mail.local.

🚀 Blackfire

Blackfire needs to use a hostname/ip that is resolvable from within the blackfire container. Their free version is limited to local profiling so we need to browse Nextcloud though its local docker IP or add the hostname to /etc/hosts.

Using with curl

alias blackfire='docker-compose exec -e BLACKFIRE_CLIENT_ID=$BLACKFIRE_CLIENT_ID -e BLACKFIRE_CLIENT_TOKEN=$BLACKFIRE_CLIENT_TOKEN blackfire blackfire'
blackfire curl http://192.168.21.8/

👥 LDAP

The LDAP sample data is based on https://github.com/rroemhild/docker-test-openldap and extended with randomly generated users/groups. For details see data/ldap-generator/. LDAP will be configured automatically if the ldap container is available during installation.

Example users are: leela fry bender zoidberg hermes professor. The password is the same as the uid.

Collabora

• Make sure to have the collabora hostname setup in your /etc/hosts file: 127.0.0.1 collabora.local
• If using SSL: set 'overwriteprotocol' => 'https' to make sure proper URLs are handed over to collabora
• Start the Collabora Online server in addition to your other containers docker-compose up -d collabora
• Make sure you have the richdocuments app cloned to your apps-extra directory and built the frontend code of the app with npm ci && npm run build
• Enable the app and configure collabora.local in the Collabora settings inside of Nextcloud

Antivirus

docker-compose up -d proxy nextcloud av

The clanav antivirus will then be exposed as a deamon with host clam and port 3310.

SAML

docker-compose up -d proxy nextcloud saml

• uid mapping: urn:oid:0.9.2342.19200300.100.1.1
• idp entity id: https://sso.local.dev.bitgrid.net/simplesaml/saml2/idp/metadata.php
• single sign on service url: https://sso.local.dev.bitgrid.net/simplesaml/saml2/idp/SSOService.php
• single log out service url: https://sso.local.dev.bitgrid.net/simplesaml/saml2/idp/SingleLogoutService.php
• use certificate from docker/configs/var-simplesamlphp/cert/example.org.crt
