Version check in the CLI #1604
Description
The gcloud CLI does this nice thing where it notifies you that there's a new version every time you run the CLI. It would be awesome if the linkerd CLI did something similar.
This should be output via. stderr (not stdout) and I'd love to have an option to silence the warning as it'll get a little annoying when you get it every time.
Here's a couple options:
There is a newer version of linkerd available. To update to the latest, please run:
$ curl https://run.linkerd.io/install | bash
To silence this warning, run:
$ linkerd config set versionCheck false
There is a newer version of linkerd available. To update to the latest, take a look at the documentation by running:
$ open https://linkerd.io/2/update
To silence this warning, run:
$ linkerd config set versionCheck false
There is a newer version of linkerd available. To update to the latest run:
$ linkerd update
To silence this warning, run:
$ linkerd config set versionCheck false
While I think the last one is the best long term solution, that has some implications that blow up the scope of this issue. Given that and the fact that there might be extended instructions, my vote is the second.
