please update docker version

[borkmann]

Current version seems to be docker 17.03 which doesn't support multi-stage builds (starting from 17.06), so for docker build I'm getting an error with Error parsing reference: [...] is not a valid repository/tag: invalid reference format. :-(

+1 here, I was trying to rebuild kaniko and ran into this:

Step 15/29 : COPY --from=0 /go/src/github.com/GoogleContainerTools/kaniko/out/executor /kaniko/executor
Unknown flag: from

Still going through proposed in xenial, shouldn't be long though

[marcoceppi]

It's a snap, why do we have to wait for Debian packaging?

[kitepad]

When is ready? I see the fix has been released at Nov. , but I still got 17.03.2 after I installed microk8s today.
Why?

[kitepad]

My ubuntu is 18.04.

Hi @kitepad

The snap is build on Ubuntu Core 16 as a base, meaning it is close to xenial 16.04.

Thanks.

@ktsakalozos Is it possible to base a snap on Core 18?
https://forum.snapcraft.io/t/ubuntu-core-18/5169

[ktsakalozos]

@andriy-f , yes It is possible to base the snap on core18. You need to edit snapcraft.yaml https://github.com/ubuntu/microk8s/blob/master/snapcraft.yaml and add a "base: core18" and rebuild. Some initial testing shows that the snap is functional but I have not tested it thoroughly. Do you want to give it a try and provide some feedback?

[dmarkey]

This would be great.. I'd like to roll this out but blocked on the docker version.

[kitepad]

@ktsakalozos, it is has been fixed : https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1794396

but still is 17.03 after I install microk8s today.

[adam-stokes]

microk8s snap needs to be rebuilt so it'll pick up the new docker. We have a job that does this automatically and shouldn't be much longer

[ktsakalozos]

A build with the 18.06 dockerd is already on edge (sudo snap install microk8s --classic --edge). Please give it a try.

Thanks

Two problems:

Invalid image name:

Warning InspectFailed 76s (x3 over 78s) kubelet, dmarkey-workstation Failed to apply default image tag "gcr.io/google_containers/defaultbackend-:1.4": couldn't parse image reference "gcr.io/google_containers/defaultbackend-:1.4": invalid reference format

➜ ~ microk8s.enable metrics-server
Enabling metrics-server
/snap/microk8s/354/usr/bin/dpkg: error while loading shared libraries: libselinux.so.1: cannot open shared object file: No such file or directory

(but still seems to work)

[dmarkey]

UPDATE: Once i install the libselinux on my host it started to work. (shouldnt all dependencies be in the snap?)

[ktsakalozos]

You are right @dmarkey, all dependencies should be in the snap. The fall back should be the host system. It is not a good time for me to debug this but I need to ask, which distro are you on?

[dmarkey]

Arch \o/

[ktsakalozos]

I knew it!

[frol]

@dmarkey yay -S libselinux did the trick! Thank you! \o/

[joestringer]

I don't think this applies any more with microk8s 1.14, which uses containerd by default.

[ktsakalozos]

Closing this since we moved to the latest containerd (1.14+) and docker packages.
