Upgrade Helm Tiller Version Used By GitLab Managed Apps
We should update to the latest version but there are some risks as the new client is incompatible with the old server so if they've already installed Tiller
then we will either need to tell them it's incompatible and they can't install new versions OR we'll need to ensure we use the appropriate helm client somehow.
I tried just upgrading this to 2.9.1
but then tested what happened with existing Tiller installed with 2.7.0
and got the following error:
Something went wrong while installing Ingress
Error: incompatible versions client[v2.9.1] server[v2.7.0]
