Neither PUB key nor PRIV key: nested asn1 error when gitlab-runner checking for jobs
Summary
After updated to 12.10.1, when gitlab-runner
try to checking for jobs, it's fail (HTTP 500 error) due to an exception in the /var/log/gitlab/gitlab-rails/api_json.log
log file (see below).
Steps to reproduce
- Update to 12.10.1
- Trying to start a new job
- Job seems to be inactive
-
/var/log/gitlab/nginx/gitlab_access.log
have an 500 error response -
/var/log/gitlab/gitlab-rails/api_json.log
have an exceptionNeither PUB key nor PRIV key: nested asn1 error
(like #32097 maybe?)
What is the current bug behavior?
It's seems that jwt.rb doesn't read the Rails.application.secrets.openid_connect_signing_key
option correctly in the lib/gitlab/ci/jwt.rb
file, line 63.
What is the expected correct behavior?
Read the Rails.application.secrets.openid_connect_signing_key
option correctly

Possible fixes
When I copy the gitlab_rails.openid_connect_signing_key
from the gitlab-secrets.json
file to directly in the /opt/gitlab/embedded/service/gitlab-rails/lib/gitlab/ci/jwt.rb
file, it's works.
Replacing:
@key ||= OpenSSL::PKey::RSA.new(Rails.application.secrets.openid_connect_signing_key)
by:
@key ||= OpenSSL::PKey::RSA.new("-----BEGIN RSA PRIVATE KEY-----\n<MY_RSA_PRIVATE_KEY_CONTENT>\n-----END RSA PRIVATE KEY-----\n")
