🏷️ Kubernetes | Cartographer | Tanzu | TAP

A note about deploying apps from source code on the Private Git Repository on the Tanzu Application Platform (TAP).

Warning

This is not the case if ootb_supply_chain_basic.gitops.commit_strategy is pull_request.

documentations are following:

Use basic authentication instead of ssh here.

table of contents

For GitHub

Create an access token for the repo as shown below.

image

Create the following Secret in the target namespace.

GIT_SERVER=github.com
GIT_USERNAME=making
GIT_PASSWORD=ghp_Nnh*******

cat <<EOF > git-basic.yaml
apiVersion: v1
kind: Secret
metadata:
  name: git-basic
  annotations:
    tekton.dev/git-0: https://${GIT_SERVER}
type: kubernetes.io/basic-auth
stringData:
  username: ${GIT_USERNAME}
  password: ${GIT_PASSWORD}
EOF

kubectl apply -f git-basic.yaml -n demo

Also set this Secret for the Service Account used by Workload.

kubectl patch serviceaccount default -p "{\"secrets\":[{\"name\":\"git-basic\"}]}" -n demo

Prepare source code on Private Git Repository. I will use the following repositories:

https://github.com/making/helloworld

image

Pass this secret to the gitops_ssh_secret parameter when creating a workload like this:

tanzu apps workload apply helloworld \
  --app helloworld \
  --git-repo https://github.com/making/helloworld \
  --git-branch main \
  --type web \
  --param gitops_ssh_secret=git-basic \
  --build-env BP_JVM_VERSION=17 \
  -n demo \
  -y

You can set the default value of the gitops_ssh_secret parameter in ootb_supply_chain_(basic|testing|testing_scanning).gitops.ssh_secret in tap-values.yaml when installing TAP

Look at the gitrepo resource and if READY is True, you can get the source code.

$ kubectl get gitrepo -n demo helloworld 
NAME         URL                                    READY   STATUS                                                            AGE

It's OK if the workload is successfully deployed.

For Bitbucket

Create an access token for the repo as shown below.

If you just want to get the source code from the Git Repository, only Read permission is fine, but this Secret is also used when writing the manifest with GitOps, so it is better to have Write permission as well.

Create the following Secret in the target namespace.

GIT_SERVER=bitbucket.org
GIT_USERNAME=tmaki_vmware
GIT_PASSWORD=ATBBg************

cat <<EOF > git-basic.yaml
apiVersion: v1
kind: Secret
