Deploy to a custom namespace 🦴

Because this is GitOps to make changes to the namespaces etc, they should really be committed to git! For example, if you wanted to create a my-ci-cd namespace for all the tooling to be deployed to, the steps are simple. Fork this repo and make the following changes there:

1. Run set-namespace.sh $ci_cd $dev $test $staging where $ci_cd $dev $test $staging are the namespaces you would like to bootstrap eg ./set-namespace.sh my-ci-cd my-dev my-test my-staging. This will update the following files:
   • bootstrap/values-bootstrap.yaml: the ci_cd_namespace and argocd namespace namespace: "my-ci-cd".
   • ubiquitous-journey/values-tooling.yaml: the destination: &ci_cd_ns my-ci-cd
   • example-deployment/values-applications.yaml: the destination: &ci_cd_ns my-dev
   • argo-app-of-apps.yaml: the destination: my-ci-cd

2. Manually update argo-app-of-apps.yaml to point source: to MY FORK instead of rht-labs. Update the branch from master to your branchname if you are not on master in your fork.

3. 🌈If there is more than one ArgoCD instance in your cluster, update instancelabel parameter to a unique value in bootstrap/values-bootstrap.yaml file. e.g: instancelabel: mycompany.com/myapps

4. Git commit this change to your fork and run the following Helm Command:

   helm template bootstrap --dependency-update -f bootstrap/values-bootstrap.yaml bootstrap   | oc apply -f -
   

   FYI if you’re feeling lazy, you can override the values on the commandline directly but rememeber - this is GitOps 🐙! So don’t do that please 😇

5. Login to ArgoCD as described in Tooling section.

6. Run argo create app replacing MY_FORK as appropriate

   argocd app create ubiquitous-journey \
    --dest-namespace my-ci-cd \
    --dest-server https://kubernetes.default.svc \
    --repo https://github.com/MY_FORK/ubiquitous-journey.git \
    --path "ubiquitous-journey" --values "values-tooling.yaml"
   argocd app sync ubiquitous-journey
   

   Or if you’re using just helm3 cli to instead of argocd cli

   helm template -f argo-app-of-apps.yaml ubiquitous-journey/ | oc apply -f -
   

If you’re looking to deploy the extra tooling too, the command is the same as above but pointing to the correct project:

argocd app create uj-extras \
    --dest-namespace my-ci-cd \
    --dest-server https://kubernetes.default.svc \
    --repo https://github.com/MY_FORK/ubiquitous-journey.git \
    --path "ubiquitous-journey" --values "values-extratooling.yaml"
argocd app sync uj-extras

1. Deploy day2ops tasks to monitor and audit the cluster

   argocd app create uj-day2ops \
    --dest-namespace my-ci-cd \
    --dest-server https://kubernetes.default.svc \
    --repo https://github.com/MY_FORK/ubiquitous-journey.git \
    --path "ubiquitous-journey" --values "values-day2ops.yaml"
   argocd app sync uj-day2ops
