Problem
You are trying to install the gitlab kubernetes agent (kas) after getting the installation instructions from the Gitlab registration, but you are getting the following error:
Error: parse error at (gitlab-agent/templates/observability-secret.yaml:1): unclosed action
Solution
This is caused by the helm version used, so upgrading the helm version works with no issues.
helm version
version.BuildInfo{Version:"v3.5.3", GitCommit:"041ce5a2c17a58be0fcd5f5e16fb3e7e95fea622", GitTreeState:"dirty", GoVersion:"go1.15.8"}
so trying to install gives the previous error.
Changing the helm version (ie with asdf)
asdf global helm 3.70
Checking the version
helm version
version.BuildInfo{Version:"v3.7.0", GitCommit:"eeac83883cb4014fe60267ec6373570374ce770b", GitTreeState:"clean", GoVersion:"go1.16.8"}
And running the helm installation again
helm upgrade --install gitlab-kas-agent gitlab/gitlab-agent \
--namespace gitlab-agent --set image.tag=v15.6.0 \
--set config.token=token_from_gitlab-registration \
--set config.kasAddress=wss://kas.domain_name.tld
Release "gitlab-kas-agent" does not exist. Installing it now.
