Branch not deleting Automatically after apply is success and PR is merged.

[ankitmahajan-appfire]

Hi team,

I have deployed the atlantis to test tf automation. Below is my config.

Server Side Repo config: repoConfig: |

repos:

• id: /.*/ delete_source_branch_on_merge: true apply_requirements: [] workflow: default allowed_overrides: [apply_requirements, delete_source_branch_on_merge] allow_custom_workflows: false

Repo Level atlantis.yaml Config version: 3 autodiscover: mode: auto delete_source_branch_on_merge: true automerge: true parallel_plan: true parallel_apply: true projects:

• dir: . terraform_version: v1.6.6 autoplan: when_modified: [".tf"] enabled: true

In both the config, i have given delete_source_branch_on_merge: true to delete the branch after everything is executed. However, same is not happening. Screenshot below.

I have also enabled the debug logs, and below are the same for above event.

Deployed with helm chart version as

appVersion: v0.28.5 version: 5.4.5

Could you please check and help here in fixing this issue?

Hi, this is a GitHub configuration: please check https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/configuring-pull-request-merges/managing-the-automatic-deletion-of-branches.

[ankitmahajan-appfire]

Hi,

That we already know. I am specificly asking for this config "delete_source_branch_on_merge: true". If we need to handle that by git config, then what is the use of this in server and repo config?

[GMartinez-Sisti]

This configuration exists for all VCS type: Github, Azure, Gitlab, etc. Looks like it's just being ignored in your configuration.

Are you using a GitHub user or a GitHub app (docs)?

[ankitmahajan-appfire]

I am using GitHub user. Created a PAT token for access and provided that in secrets.

[GMartinez-Sisti]

My best guess is that Atlantis is not getting the webhook for the merge event. Can you confirm the events you have configured (docs)?

[ankitmahajan-appfire]

In the configured the webhook as per the documentation and select 4 checkboxes as mentioned.

Below are the webhooks that are getting triggerred

I don't see any event for merge

[GMartinez-Sisti]

The most strange part is that Atlantis log doesn't show any event or failure for that event. We might have a bug or something is missing.

@jamengual can you move this issue into https://github.com/runatlantis/atlantis pls?

[ankitmahajan-appfire]

Thanks @GMartinez-Sisti for considering. @jamengual pls take this up and release the fix

[GMartinez-Sisti]

pls take this up and release the fix

@ankitmahajan-appfire not quite like this 😅 first we need to see if it's actually a bug or if someone is able to use it correctly. Then since this an open source project someone will need to volunteer to pick it up. But at least it's a start 😃

[ankitmahajan-appfire]

Sure @GMartinez-Sisti . Thanks
