GitLab💣
Gitlab for Kubernetes💣
gitlab provides the upstream documentation:
GitLab is a web-based DevOps lifecycle tool that provides a Git-repository manager providing wiki, issue-tracking and continuous integration/continuous deployment pipeline features, using an open-source license, developed by GitLab Inc.
Application Deployment💣
The default values are intended for development, demo, and CI pipelines. For operational/production environments see the suggestions in docs/operational-production-settings.md.
Kubernetes resource configuration💣
The BigBang Gitlab Package has a default resource configuration for a minimal installation which is sufficient for development, demos, and CI pipelines. For larger operational deployments you must increase the CPU and memory as needed. See suggested production settings here docs/operational-production-settings.md. Consult the upstream Gitlab documentation and Gitlab Support for appropriate settings. See the docs/k8s-resources.md for a list of all possible configuration values.
Keycloak SSO integration💣
Gitlab SSO integration can be 100% configuration as code. No manual post-install actions are required if the configuration is correct. see docs/keycloak.md
elasticsearch notes💣
create an index pattern for fluentd if not already created for you

Here is a document that lists the Gitlab components and what each one does
https://docs.gitlab.com/ce/development/architecture.html#component-details
Here are some an examples of a filter for a secific containers:
front-end webservice
{
"query": {
"match_phrase": {
"kubernetes.container_name": "webservice"
}
}
}
gitlab-workhorse - a gateway for routing http requests to the proper component
{
"query": {
"match_phrase": {
"kubernetes.container_name": "gitlab-workhorse"
}
}
}
cli git commands
{
"query": {
"match_phrase": {
"kubernetes.container_name": "gitlab-shell"
}
}
}
In the KQL field you can text search within a source field such as log
log: "error"
