Docker Image for Bruno

This project contains a Dockerfile to build an image for Bruno, a tool for testing and exploring web APIs.

Build

You can build the image from the remote Git repo, without having to check it out even:

docker build -t bruno-image github.com/davidkarlsen/bruno-image

Download

There is a prebuilt image available in the GitHub Container Registry, so you can simply use that:

# fetch image
docker pull ghcr.io/davidkarlsen/bruno-image:main

Usage

Plain Docker

# get help output
docker run --rm ghcr.io/davidkarlsen/bruno-image:main help
# run on the collection in the current directory
docker run --rm --volume .:/tests --workdir /tests ghcr.io/davidkarlsen/bruno-image:main

Docker Compose

You can integrate this as a service to run the tests (typically against other services in the setup) in the isolation of a container.

version: '3.6'

services:
  bruno:
    build: github.com/davidkarlsen/bruno-image:main
    # set working dir to the directory with the test collection
    working_dir: /tests
    volumes:
      # mount test collection into the container
      - type: bind
        source: .
        target: /tests
    profiles:
      # set a profile to prevent this from being started by default
      - bruno

# fetch help output
docker compose run bruno help
# run bruno on the collection in the mounted directory
docker compose run bruno

Troubleshooting

Error "You can run only at the root of a collection"

Chances are that you forgot to mount the test collection into the container's working directory. Double-check that this is set up correctly. Another possible mistake is that you simply haven't started writing a test collection yet. The bru CLI identifies a test collection by this file. An empty JSON object ("{}") as content is enough.
