Installation
binary
Krab binary can be downloaded from GitHub. Other methods are listed below.

Krab provides asdf plugin (make sure you have asdf updated):

docker
Docker images can be found at GitHub packages.
To start a docker container a DATABASE_URL environment variable must be provided.
By default “krab” reads configuration from /etc/krab that must be mounted as a volume,
the path can be changed by KRAB_DIR environment variable.
Pull the docker image:
docker pull ghcr.io/ohkrab/krab:nightly
Example:
docker run --rm \ # remove container after command execution
-e DATABASE_URL="..." \ # provide connection string
-v ${HOME}/project1:/etc/krab:ro \ # mount configuration volume
ghcr.io/ohkrab/krab:nightly version # run `version` command from `qbart/krab:latest`
one-liner:
docker run --rm -e DATABASE_URL="..." -v ${HOME}/project1:/etc/krab:ro ghcr.io/ohkrab/krab:nightly version
