Tag for Release Candidates? [Answered]

I noticed v2.0.0-rc1 and v2.0.0-rc2 pop up in releases, but I can’t pull them. Since others have it working, I guess I’m just missing the right tag.

With:

docker run -p 80:80 -p 443:443 -d rancher/server:v2.0.0-rc2

I get:

Unable to find image 'rancher/server:v2.0.0-rc2' locally
docker: Error response from daemon: manifest for rancher/server:v2.0.0-rc2 not found.

They are in rancher/rancher, which we will be moving to in order to reduce (/create different) confusion with latest and stable for 1.x vs 2.x.

Ah ha. That does seem cleaner considering the 1.6.x will remain for a while. Worked.

docker run -p 80:80 -p 443:443 -d rancher/rancher:v2.0.0-rc2

Did the functionality of --acme-domain change? That bit no longer appears to be working for me, but that could be a Cloudflare thing too.

No, it hasn’t changed…

–acme-domain is not working for me either

Let’sEncrypt works fine. It is only for the standalone server, it is not for trying to do HA or run inside k8s as an ingress.
