I need to install simple packages such as curl inside a running container but I face this error:
~ $ apk add curl
ERROR: Unable to lock database: Permission denied
ERROR: Failed to open apk database: Permission denied
I know how to chnage the user in a Dockerfile but I don't have access to the docker file and I need to do it while I am inside the container or when opening a terminal inside the container. I tried to use --user=
but didn't work:
kubectl exec -n kube-system --user="root" -it tiller-deploy-75f6c87b87-xtpxl /bin/ash
error: auth info "root" does not exist
How I can get root access or install curl?
Is your user sudoer? Run this command:
sudo apk add curl
And if the above command didn't work, run this command.
docker exec -it CONTAINER_NAME apk add curl
