See https://gitlab.com/gitlab-org/charts/gitlab/-/blob/master/doc/installation/upgrade.md for more details. === NOTICE You've installed GitLab Runner without the ability to use 'docker in docker'. The GitLab Runner chart (gitlab/gitlab-runner) is deployed without the `privileged` flag by default for security purposes. This can be changed by setting `gitlab-runner.runners.privileged` to `true`. Before doing so, please read the GitLab Runner chart's documentation on why we chose not to enable this by default. See https://docs.gitlab.com/runner/install/kubernetes.html#running-docker-in-docker-containers-with-gitlab-runners Help us improve the installation experience, let us know how we did with a 1 minute survey:https://gitlab.fra1.qualtrics.com/jfe/form/SV_6kVqZANThUQ1bZb?installation=helm&release=15-3 === NOTICE The in-chart NGINX Ingress Controller has the following requirements: - Kubernetes version must be 1.19 or newer. - Ingress objects must be in group/version `networking.k8s.io/v1`.
