Since yesterday my builds with the apk package are failing.

It looks like you are essentially mixing the edge community repository with the 3.3 main repository. 3.3 doesn’t have the libseccomp package, so it fails.

I can’t say that I’m experienced enough with alpine to give you terribly qualified best practices advice, but it seems like it would be ideal to run alpine edge instead of 3.3 if you want edge packages.

other than that, I was able to get the edge docker version installed on alpive 3.3 by doing the following:

$ apk --no-cache add --repository http://dl-cdn.alpinelinux.org/alpine/edge/main libseccomp
$ apk --no-cache add --repository http://dl-cdn.alpinelinux.org/alpine/edge/community docker

or in one command:

$ apk add --no-cache  --repository http://dl-cdn.alpinelinux.org/alpine/edge/main --repository  http://dl-cdn.alpinelinux.org/alpine/edge/community  docker

That worked like a charm. As you can see i am also not very experienced using alpine. But this took me a step further.

Many thanks,
