Sandbox macro operations

[HOME]

You can run a command in several sandboxes at once, using the global command, which propagates your command to all the installed sandboxes.

$ dbdeployer global -h 
This command can propagate the given action through all sandboxes.

Usage:
  dbdeployer global [command]

Examples:

	$ dbdeployer global use "select version()"
	$ dbdeployer global status
	$ dbdeployer global stop --version=5.7.27
	$ dbdeployer global stop --short-version=8.0
	$ dbdeployer global stop --short-version='!8.0' # or --short-version=no-8.0
	$ dbdeployer global status --port-range=5000-8099
	$ dbdeployer global start --flavor=percona
	$ dbdeployer global start --flavor='!percona' --type=single
	$ dbdeployer global metadata version --flavor='!percona' --type=single
	

Available Commands:
  exec             Runs a command in all sandboxes
  metadata         Runs a metadata query in all sandboxes
  restart          Restarts all sandboxes
  start            Starts all sandboxes
  status           Shows the status in all sandboxes
  stop             Stops all sandboxes
  test             Tests all sandboxes
  test-replication Tests replication in all sandboxes
  use              Runs a query in all sandboxes

Flags:
      --dry-run                Show what would be executed, without doing it
      --flavor string          Runs command only in sandboxes of the given flavor
  -h, --help                   help for global
      --name string            Runs command only in sandboxes of the given name
      --port string            Runs commands only in sandboxes containing the given port
      --port-range string      Runs command only in sandboxes containing a port in the given range
      --short-version string   Runs command only in sandboxes of the given short version
      --type string            Runs command only in sandboxes of the given type
      --verbose                Show what is matched when filters are used
      --version string         Runs command only in sandboxes of the given version

Using global, you can see the status, start, stop, restart, test all sandboxes, or run SQL and metadata queries.

The global command accepts filters (as of version 1.44.0) to limit which sandboxes are affected.

The following sub-commands are accepted:

• exec Runs a command in all sandboxes.
• metadata Runs a metadata query in all sandboxes
• restart Restarts all sandboxes
• start Starts all sandboxes
• status Shows the status in all sandboxes
• stop Stops all sandboxes
• test Tests all sandboxes
• test-replication Tests replication in all sandboxes
• use Runs a query in all sandboxes

dbdeployer global exec

Runs a command in all sandboxes. The command will be executed inside the sandbox. Thus, you can reference a file that you know should be there. There is no check to ensure that a give command is doable. For example: the command cat filename will result in an error if filename is not present in the sandbox directory. You can run complex shell commands by prepending them with either bash -- -c or sh -- -c. Such command must be quoted. Only one command can be passed, although you can use a shell command as described above to overcome this limitation. IMPORTANT: if your command argument contains flags, you must use a double dash (--) before any of the flags.

You may combine the command passed to exec with other drill-down commands in the sandbox directory, such as ./exec_all. In this case, you need to make sure that all your sandbox contain the command, or use --type to only run exec in the specific topologies.

dbdeployer global use

Runs a query in all sandboxes. It does not check if the query is compatible with every version deployed. For example, a query using @@port won't run in MySQL 5.0.x

Usage: dbdeployer global use {query} [flags]

Example: $ dbdeployer global use "select @@server_id, @@port"
