Clojure dockerized

Spin up the docker container

Run

docker-compose -f clj-dev/docker-compose.yaml run --entrypoint "/bin/bash" clojure

Run as program

Inside the container, run

root@bxyz:/usr/local/app# make run
{:some "data"}

REPL

To get a REPL, run

root@xyz:/usr/local/app# clj
Clojure 1.11.1
user=> (require 'main) ; or (require 'main :reload) 
                       ; or (require 'main :reload-all) after you've made some changes
nil
user=> (main/read-json "data.json")
{:some "data"}

Use ctrl+d or ctrl+d to exit from the Clojure REPL and then ctrl+d or type exit to exit from the docker container.

nREPL

In the host system, figure out how to obtain the ip address of the running docker container.

Inside the container, run

root@xyz:/usr/local/app# make nrepl

VSCode

In the host system in your VSCode

REPL
- Connect to a running REPL in your project
  - Generic

Voilà!
