I'm trying to execute lein run in a Clojure Docker image out of a mounted folder that is not /, but when I try to cd into a folder, Docker complains with unable to locate cd:
docker run -v /root/chortles:/test -i jphackworth/docker-clojure cd /test && lein run
=> Unable to locate cd
How do I instruct Leiningen to run in a different folder, or tell Docker to change the directory prior to running my command?
You can use -w param for docker run. This parameter is useful for specifying working directory within container.
docker run -w /test -v /root/chortles:/test -i jphackworth/docker-clojure lein run
The best bet is to add a shell script to the docker image and call that.
Have a script called, say lein-wrapper.sh, install in in /usr/local/bin. The script should sort out the environment for leiningen and then call it. Something like this:
#!/bin/sh
export PATH=${LEININGEN_INSTALL}:${PATH}
cd /test
lein $@
You can set
ENTRYPOINT["/usr/local/bin/lein-wrapper.sh"]
In your Dockerfile
And invoke it as:
# Will call /usr/local/bin/lein-wrapper.sh run
# which will call lein run
docker run -v /root/chortles:/test -i jphackworth/docker-clojure run
# or run lein deps...
docker run -v /root/chortles:/test -i jphackworth/docker-clojure deps
cd is a bash builtin, not a command. You can use bash -c 'cd /test && lein run'. Better yet, do as @Jiri states and use the -w parameter to set the working directory of the container, then just use lein run to start your app.
