Migrating variables to Git

Last updated

Support for storing non-sensitive variables in Git will be available to everyone in an upcoming version of Octopus. All newly configured Git projects will automatically have variables migrated when converting the project to Git. For existing Git projects, you will need to migrate these manually.

We recommend migrating your variables to Git as soon as practical. We will continue to support Git projects with variables that haven't been migrated for now, but we will remove support for this at some point in the future.

This document covers the process of migrating variables to Git. You will need to migrate the variables for each existing Git project separately.

Preparing to migrate

Check that all secrets are marked as sensitive

All non-sensitive values will be written to your Git repository in plain text during the migration. Before migrating, ensure that you do not have any secret values that are not stored as sensitive variables.

If you can view a value on the variables page (and it's not shown as a password field) or retrieve the value from the API, it's not marked as sensitive and will be written to the variables.ocl file.

Coordinate with your team

After you have run the migration, you will be unable to read variables from any Git reference (branch, tag, or commit) that does not contain a valid variables.ocl file. This will cause failues when viewing and editing variables, creating releases, and running runbooks using those references until they're updated.

The migration process only writes the variables to a single branch. To continue using variables in any other branches, you will need to merge that migration branch with your other branches to continue using them in Octopus. If this may disrupt your team, plan ahead and find a suitable time to migrate and merge.

Running the migration

The migration process is simple, and we've built a helpful wizard to guide you through it. If this feature is available in your instance and you have a project that does not yet have variables in Git, you will see this banner on the project variables page.

Clicking the Migrate Variables To Git button will open the migation wizard.

Step 1: Getting started

The first page is just informational. After opening the dialog, Octopus will validate that the project can migrate variables to Git, then you can continue.

Step 2: Select a branch

Always use the default branch if possible. The default branch is the first branch shown when new users view the project, and Octopus only snapshots variables from the default branch for Runbooks. You always want to have a valid variables file on the default branch, so migrate directly there if you can.

If you are unable to migrate to the default branch (for example, it's protected), you can select any other branch or get Octopus to create a new branch from the default when migrating. Once the migration is finished, merge the variables to the default branch as soon as possible.

Step 3: Review & migrate

After selecting the branch, you can view the migration summary and start the migration. The migration is typically completed in a few seconds.

Once the migration is complete, click Done. The project will reload, and your variables will now be in Git.

Next steps

Merge variables to the default branch

If you migrated the variables to any branch other than the default, be sure merge the variables to the default branch immediately. The variables are now just like any other file in your Git respository, so follow your typical Git workflows to get this merged.

Update any other branches

If you're a frequent user of branching within Octopus, you will want to ensure you get the variables to all of your active branches as quickly as possible.

Once the variables have been merged to the default branch, you can update your branches as you would with any other files in your repository - pull the latest changes into your branch, and you'll be good to go.
