Usage

prerequisites

Create and export GitLab access token to environmental variables as follows:

export KSNOTIFY_GITLAB_TOKEN="xxxxxx"

ref: Project access tokens | GitLab

Post diff results to GitLab

Basic usage is as follows:

skaffold render -p dev | kubectl diff -f - 2> /dev/null | | ksnotify --notifier gitlab --ci gitlab

If you want to update existing comment instead of create a new comment, you should add --patch flag like

skaffold render -p dev | kubectl diff -f - 2> /dev/null | | ksnotify --notifier gitlab --ci gitlab --patch

To suppress skaffold labels like skaffold.dev/run-id: 1234 automatically added by skaffold, you should add --suppress-skaffold flag like

skaffold render -p dev | kubectl diff -f - 2> /dev/null | | ksnotify --notifier gitlab --ci gitlab --suppress-skaffold

The concrete example of GitLab CI configuration is shown in example.

For developers

To run ksnotify locally, use local option for debug. For local mode, ksnotify just renders contents on stdout.

skaffold render -p dev | kubectl diff -f - 2> /dev/null | ~/Dev/ksnotify/ksnotify --ci local --notifier gitlab --suppress-skaffold
