I am trying to set the current context of the cluster using shell script.
#!/usr/bin/env bash
#Set Parameters
echo ${cluster_arn}
sh "aws eks update-kubeconfig --name abc-eks-cluster --role-arn ${cluster_arn} --alias abc-eks-cluster"
export k8s_host="$(kubectl config view --minify | grep server | cut -f 2- -d ":" | tr -d " ")"However, the above command gives error:
sh: 0: Can't open aws eks update-kubeconfig --name abc-eks-cluster --role-arn arn:aws:iam::4399999999873:role/abc-eks-cluster-cluster-admin --alias abc-eks-cluster
Can someone suggest me how do what is the issue and how can I set the current context because the k8_host command yiedls another error that context is not set.
I have no idea why you are even involving sh as a subshell, when you're already in a shell script, but
Can someone suggest me ... what is the issue
You have provided the entire command to sh but failed to use the -c that informs it that the first argument is an inline shell snippet; otherwise, sh expects that the first non-option argument is a file which is why it says it cannot open a file with that horrifically long name
There are two outcomes to get out of this mess: use -c or stop trying to use a subshell
sh -c "aws eks update-kubeconfig --name abc-eks-cluster --role-arn ${cluster_arn} --alias abc-eks-cluster"or:
aws eks update-kubeconfig --name abc-eks-cluster --role-arn ${cluster_arn} --alias abc-eks-cluster
