IAM user inside 1doc3 user group ArchitectureManagers.

AWS CLI command line tool installed and configured.

jq command line tool installed.

access to 1DOC3/argocd project repository.

kubectl 1.23 command installed.

Procedure

Inside 1DOC3/argocd repository, you can use the script ./utilities/assume-role.sh to assume KubeAdmin IAM role. Before executing the script be sure that the script has execution permissions. To do that, run the next command in the root of the project:

> chmod +x ./utilities/assume-role.sh

Then run the next command to assume the role KubeAdmin:

> ./utilities/assume-role.sh -s KubeAdmin -p ptest3 -d 28000 -a arn:aws:iam::350572149155:role/KubeAdmin

The argument p sets the profile that will be used to save the assumed credentials. The argument d will be used to set the expiration time of the credentials token.

Finally use the next command to configure kubectl

> aws eks update-kubeconfig --name staging --profile ptest3 --region us-east-1
