🐳 Add annexes to container

[pschmitt]

Here are a few updates to the docker container.

• annexes get installed by default
• zinit completion
• at container build time @zinit-scheduler burst now installs to /data-static
• at runtime /data-static gets copied over to /data. This is necessary because /data is meant to be backed via a volume (that's what we do in the zunit tests for instance to verify if we downloaded the files correctly)
• most of the custom stuff (keys setup, annexes, the /data-static to /data file-copy etc) can now be disabled with NOTHING_FANCY=1 at runtime

Did this break something with zsh 5.1?

[pschmitt]

Nah, that's just GH runners getting stuck.

Seems related: zsh-users/zsh-docker#21

zsh 5.1.1 is for sure a trouble-maker, its build log ends with "build failed":

https://github.com/zdharma-continuum/zinit/runs/4292608375?check_suite_focus=true#step:7:6245

The image kinda works though:

docker run -it --rm ghcr.io/pschmitt/zinit:zsh-5.1.1 zsh --version
zsh 5.1.1 (x86_64-unknown-linux-gnu)

Maybe we should drop zsh 5.1.1 altogether. zinit works best with 5.5.1+ anyway.

[alichtman]

Yeah, let's drop it. It's old enough.
