Gogs

A production optimised version of Gogs, able to run in --read-only mode. The only caveat is that you need to mount the s6 volume (to make it writable) as s6 will need to do some writing.

Other services that run on the image:

• crond
• ssh (port 22222)

Running in read-only mode

Runs using a user git:801, so there are a number of options for running the container...

1. Create a host user with matching UID:

sudo useradd --no-create-home --system --shell /bin/false --uid 801 foo

docker run \
    --name gogs \
    --rm \
    --read-only \
    --tmpfs /tmp:rw,size=***k \
    -v /var/gogs/config:/config:ro \
    -v /var/gogs/data:/data \
    -v /var/gogs/s6:/var/run/s6 \
    -p 127.0.0.1:22:22222 \
    -p 127.0.0.1:3000:3000 \
    --cpus=".3" \
    --memory="250m" \
    --pids-limit 50 \
    --security-opt="no-new-privileges:true" \
    --health-cmd="curl --fail http://localhost:3000/healthcheck || exit 1" \
    --health-interval=5s \
    --health-retries=3 \

2. Mount /etc/passwd and create a host user with matching name:

sudo useradd --no-create-home --system --shell /bin/false git

docker run \
    --name gogs \
    --rm \
    --read-only \
    --tmpfs /tmp:rw,size=***k \
    -v /etc/passwd:/etc/passwd:ro \
    -v /var/gogs/config:/config:ro \
    -v /var/gogs/data:/data \
    -v /var/gogs/s6:/var/run/s6 \
    -p 127.0.0.1:22:22222 \
    -p 127.0.0.1:3000:3000 \
    --cpus=".3" \
    --memory="250m" \
    --pids-limit 50 \
    --security-opt="no-new-privileges:true" \
    --health-cmd="curl --fail http://localhost:3000/healthcheck || exit 1" \
    --health-interval=5s \
    --health-retries=3 \

Running in writable mode

It is possible to define a UID and GID to the container but --read-only won't be possible as it modifies /etc/passwd. This is done using usermod (via the shadow package in alpine):

docker run \
    --name gogs \
    --rm \
    -e UID=$(id -u) \
    -e GID=$(id -g) \
    -v /var/gogs/config:/config:ro \
    -v /var/gogs/data:/data \
    -p 127.0.0.1:22:22222 \
    -p 127.0.0.1:3000:3000 \
    --cpus=".3" \
    --memory="250m" \
    --pids-limit 50 \
    --health-cmd="curl --fail http://localhost:3000/healthcheck || exit 1" \
    --health-interval=5s \
    --health-retries=3 \

Set your own UID/GID during build

As a final option, should you wish, you can specify your own UID and GID for the git user when building the image.

docker build \
    --build-arg=UID=1234 \
    --build-arg=GID=5678 \
    -t gogs .
