GitLab Runner certificate signed by unknown authority
Contents
Recently I’ve been working w/ GitLab Runners, starting with Shell Executor before moving on to Docker.
Self-signed
Anyway, my GitLab instance uses a self-signed certificate. This is not great as our tooling essentially needs to work around errors like this:
ERROR: Registering runner... failed runner=EfnphyLc status=couldn't execute POST against https://example.com/api/v4/runners: Post https://example.com/api/v4/runners: x509: certificate signed by unknown authority
PANIC: Failed to register this runner. Perhaps you are having network problems
Config
In your config.toml, introduce GIT_SSL_NO_VERIFY=true in your list of environment variables; e.g.,
concurrent = 1
check_interval = 0
[[runners]]
name = "f6705c062106"
url = "FIXME"
token = "FIXME"
executor = "docker"
environment = ["GIT_SSL_NO_VERIFY=true"]
[runners.docker]
tls_verify = false
image = "FIXME"
privileged = false
disable_cache = false
volumes = ["/cache"]
pull_policy = "if-not-present"
shm_size = 0
[runners.cache]
NB: Not saying that this is a good practice, merely a workaround.
