In this lab the student is guided through several Kubernetes and Flux commands that may prove useful when operating and troubleshooting Flux in the subsequent labs in this course.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Analyze The YAML Used To Install Flux
To output the yaml that is applied by kubectl, simply use the same command and either display it or route it to a file instead of piping it to kubectl.
$ fluxctl install --git-user=${GHUSER} --git-email=${GHUSER}@users.noreply.github.com --git-url=git@github.com:${GHUSER}/content-gitops --git-path=namespaces,production --namespace=fluxThis output has also been placed in a file within the docs folder on the course repo, and is at this link:
https://github.com/linuxacademy/content-gitops/blob/master/docs/Flux_Install_Yaml.md- Display the log produced by the fluxd Daemon
To display the log produced by the fluxd daemon running as a deployment in your cluster, enter the command:
$ kubectl -n flux logs deployment/fluxThis assumes you have deployed flux to the flux namespace.
- Display details about the flux pod running
To display details about the pod deployed in your cluster, first obtain the unique pod name with the following command:
$ kubectl -n flux get podsThen copy the unique pod name to your clipboard and input:
$ kubectl -n flux describe pod [your flux pod name here]Example command with sample pod name:
kubectl -n flux describe pod flux-c97899756-wsfhb
