Use the check to confirm when a specific context or a context that matches a specific pattern is present on all changesets. More specifically, UserDefinedContextCheck uses a regular expression to setup an enumeration for a customer’s existing environments so they use the correct values.

Use UserDefinedContextCheck

Prerequisites

  1. Ensure that you have correctly specified your Liquibase Pro license key.
  2. Ensure that the --checks-scope parameter includes the scope of this check.

For example:

--license-key=<string>
--checks-scope=<string>
globalArgs: { license-key: "<string>" }
cmdArgs: { checks-scope: "<string>" }
liquibase.licenseKey: <string>
liquibase.command.checksScope: <string>
liquibase.licenseKey: <string>
liquibase.command.checks.run.checksScope: <string>
JAVA_OPTS=-Dliquibase.licenseKey=<string> -Dliquibase.command.checksScope=<string>
JAVA_OPTS=-Dliquibase.licenseKey=<string> -Dliquibase.command.checks.run.checksScope=<string>
LIQUIBASE_LICENSE_KEY=<string>
LIQUIBASE_COMMAND_CHECKS_SCOPE=<string>
LIQUIBASE_LICENSE_KEY=<string>
LIQUIBASE_COMMAND_CHECKS_RUN_CHECKS_SCOPE=<string>

Enable

This check is disabled by default. To enable it, run the enable command:

liquibase checks enable --check-name=<string>

When you try to enable the check, Liquibase displays the following message:

This check can not be enabled directly because one or more fields does not have a default value.  Create a copy of this check and initiate the customization workflow.

Liquibase then prompts you to specify a name for the new check. By default, the name of the copy is <CheckName>1. You can use the default value by pressing Enter or you can specify a custom name.

Customize

This check is dynamic, meaning you can customize its settings. See the table on this page for more information.

  1. Once you've enabled the check, follow the steps in the CLI to set new values:
    • Default values are shown in [brackets]. You can use these by pressing Enter. Alternatively, specify custom values.
    • If a customization setting does not have a default value, you must specify custom values.
  2. When finished, verify that your configuration is correct by running the show command:
    3. liquibase checks show --check-name=<string>
  3. If you need to make any other changes, run the customize command:
    4. liquibase checks customize --check-name=<string>

    Note: If you want to create another variant of this check with different settings, use the copy command to create a copy of the original check and then use the customize command to customize it.

Run

To run the check, use the run command:

liquibase checks run --check-name=<string>
stages:
  Default:
    actions:
      - type: liquibase
        command: checks run
        cmdArgs: {check-name: <string>}

And then run the flow command on your flow file:

liquibase flow
