liquibase-preconditions-contexts-labels

This sample application demostrates the usage of preconditions, contexts and labels in liquibase.

Prerequisites

• Liquibase - 3.8
• PostreSQL JDBC driver (for postgreSQL Database; for other databases use other compatible drivers)

Schema Details

This application has the scripts to create these tables, relations and add dummy data. The scripts are configured to cater to 3 environments,

• Development environment - has database constraints.
• Test environment - has database constraints, has fake data.
• Production environment - does not have database constraints.

Configuration

1. Update the following parameters in the liquibase.properties file
   • url
   • username
   • password
   • classpath
   • driver (incase a different database is used)
2. A dbms precondition has been configured in the master.changelog.xml to run the liquibase changelogs only on postgreSQL database. You can change it to your particular database.

Execution

To apply the changes to an existing database, run the following command in the base directory of the project.

liquibase update

This will run all the changesets. To run a the changesets for a particular environment, specify the particular context,

liquibase --contexts=dev,test update
