mysql-cli-plugin

The mysql-tools plugin can be used to migrate a p-mysql (v1) service instance to a p.mysql (v2) service instance.

Installation

A binary version of the plugin can be installed from the CF-Community plugin repository:

$ cf install-plugin -r CF-Community MysqlTools

Usage

Once the plugin is installed, migrate a v1 service instance to a new v2 service instance with the following command:

$ cf mysql-tools migrate V1-INSTANCE V2-PLAN

Where V1-INSTANCE is the name of the v1 service instance that you wish to migrate, and V2-PLAN is the name of the v2 service plan to use for the new v2 service instance.

This will create a new v2 service instance and copy the data from the v1 service instance into it.

At the end of this operation, the v2 service instance will have the same name as the original v1 service instance (V1-INSTANCE), and the v1 instance will have -old appended to its name.

More detailed instructions are available in the VMware SQL with MySQL for Tanzu Application Service Documentation.

Some Notice:

  • Stop all apps bound to the service instance before migrating.
  • The Database instance should not be receiving any write traffic while the migration is happening.
  • The apps bounded to the original v1 service instance need to be manually bound to the new v2 service instance at the end of the migration.
  • There will be token timeout messages when migrating lots of data, which can be ignored.

Building

Prerequisites

  1. cd into the root directory of the project.

  2. Run the following script to build the mysql binary and other assets, generate golang fixtures, and compile the binary

    $ ./scripts/build-plugin

Testing

Running unit tests

Prerequisites

Some of the tests use Docker to integrate with a MySQL database and require the docker cli and a local docker daemon for spinning up containers.

$ ./scripts/run-unit-and-docker-tests

Running System Tests

Prerequisites

System tests interact with a real environment running Cloudfoundry, for instance a bosh-bootloader environment with cf-deployment.

System tests assume the plugin provided by this repo has already been installed. To run these tests you should:

  1. Install the cli plugin

     $ ./scripts/build-plugin
 $ cf install-plugin -f ./mysql-cli-plugin

  2. Run the test script

    $ ./scripts/run-specs

    Specific tests can be run by passing ginkgo filtering options to the underlying script.

    Example

    $ ./scripts/run-specs --label-filter="smoke_test"
