I want to use a recent `git-annex` version, and I prefer a Docker solution to a binary. There wasn't much documentation on how to do that, so here are the steps I took, just in case anybody finds this information useful. This is not a complete guide, just more than I was able to find so far.
|
|
|
|
- Install Docker so that you can access it (eg, `docker info`) without `sudo`. (Beyond the scope in here.)
|
|
|
|
- Create a git-annex image as follows:
|
|
|
|
Dockerfile:
|
|
|
|
FROM debian:unstable
|
|
RUN apt-get update && apt-get install -y ssh git man git-annex=6.20160511-1
|
|
# maybe install gpg2, other remotes, etc
|
|
#RUN apt-get install -y gnupg2 && ln -s /usr/bin/gpg2 /usr/local/bin/gpg
|
|
#RUN apt-get install -y golang-go && GOPATH=/usr/local go get github.com/encryptio/git-annex-remote-b2
|
|
VOLUME /data
|
|
WORKDIR /data
|
|
|
|
Build image and run basic test:
|
|
|
|
docker build -t git-annex-6.20160511-1 .
|
|
docker run -it --rm git-annex-6.20160511-1 git-annex version
|
|
|
|
- You still need to:
|
|
|
|
- On host: Replace `git-annex` by a script that invokes the Dockerized version.
|
|
- In container:
|
|
- Use non-root uids, otherwise you end up creating files with uid 0.
|
|
- Access `ssh` and `gpg` credentials on host.
|
|
- Access `~/.gitconfig` on host.
|
|
- Mount `git` repository root as a volume, not just the current dir.
|
|
- Access AWS/B2 credentials, if applicable.
|
|
|
|
Here is a sample script that achieves these. Name it `git-annex`, and place it in your `PATH` before the host `git-annex` (or just uninstall the latter).
|
|
|
|
#!/bin/bash
|
|
CONT_NAME=${CONT_NAME:-git-annex-6.20160511-1}
|
|
# if in git repo, mount root as /data, and cd into relative subdir
|
|
# if not, mount cwd as /data
|
|
abs_dir=$(readlink -e .)
|
|
root_dir=$(git rev-parse --show-toplevel 2>/dev/null || true)
|
|
root_dir=${root_dir:-$abs_dir}
|
|
rel_dir=${abs_dir#$root_dir}
|
|
# if run by git, assume command is git-annex
|
|
# otherwise, don't assume, to allow other uses
|
|
cmd=
|
|
! [ \"$(basename \"$(readlink -e /proc/$PPID/exe)\")\" = \"git\" ] || cmd=git-annex
|
|
exec docker run -it --rm \
|
|
-u $(id -u):$(id -g) \
|
|
-v /etc/passwd:/etc/passwd:ro \
|
|
-v $HOME/.ssh:$HOME/.ssh \
|
|
-v $HOME/.gnupg:$HOME/.gnupg \
|
|
-v $HOME/.gitconfig:$HOME/.gitconfig \
|
|
-v \"$root_dir\":/data \
