These Katacoda scenarios are based on https://concoursetutorial.com/ by Stark & Wayne

We have learned the basic concept of setting up the concourse command line client, some basic commands and the environment used for this course.

Client and Course Setup

Step 1 of 2

Getting Started

To run Concourse we need postgres and some basic configuration, we can launch both using the docker-compose file provided and docker-compose commands further down below.

Refer to the Docker courses to learn more about Docker.

For the purpose of this scenario, we need to provide concourse with a valid external URL of this learning environment:

echo "CONCOURSE_EXTERNAL_URL=https://[[HOST_SUBDOMAIN]]-8080-[[KATACODA_HOST]].environments.katacoda.com" >> concourse.env

You may review the configuration used here:

cat concourse.env

Next, stand up both Postgres and Concourse in quickstart mode with:

docker-compose up -d

Wait for compose to pull the docker images and stand up the database as well as the concourse UI / scheduler and workers.

After the compose process finished, it may still take a minute for the concourse dashboard to appear in the upper frame.

If the terminal is available, let's download the command line client while waiting for the UI:

curl -Lo fly.tar.gz https://github.com/concourse/concourse/releases/download/v5.0.0/fly-5.0.0-linux-amd64.tgz

Extract

tar -xzf fly.tar.gz && rm fly.tar.gz

And put under /usr/local/bin which is by default on $PATH

mv fly /usr/local/bin/

If the dashboard became available, use the following credentials to log in with a local user (as you may have guessed from reviewing the concourse.env file earlier):

  • User: admin
  • Password: admin

For more advance configuration of authentication with identity providers such as GitHub, GitLab, BitBucket, LDAP or generic OIDC ... refer to the Authentication documentation which is out of scope for this course.

Next we will configure our command line client to work with our local concourse instance.
