|
* Introduction
|
|
|
|
This document captures the setup steps for a 90-minute, hands-on Ruby On Rails workshop on Openshift.
|
|
|
|
Within the session, participants will:
|
|
- Work with a Ruby codebase in Bitbucket.
|
|
- Deploy the application on Openshift.
|
|
- Create continuous delivery pipelines with Tekton.
|
|
|
|
* Pre-requisites
|
|
|
|
This guide assumes you have an existing Openshift 4.10+ cluster with cluster admin permissions.
|
|
|
|
* 1 - Preparing the cluster
|
|
|
|
1. Log in to the cluster in your terminal with the ~oc~ cli.
|
|
|
|
#+begin_src bash
|
|
oc login --server <URL> --token <TOKEN>
|
|
#+end_src
|
|
|
|
* 2 - Deploy Bitbucket
|
|
|
|
Now that we're logged into the cluster, let's create the namespace to deploy Bitbucket into.
|
|
|
|
#+begin_src bash :results output
|
|
oc new-project bitbucket
|
|
#+end_src
|
|
|
|
#+RESULTS:
|
|
#+begin_example
|
|
Already on project "bitbucket" on server "https://api.rosa-7lpn7.2pqm.p1.openshiftapps.com:6443".
|
|
|
|
You can add applications to this project with the 'new-app' command. For example, try:
|
|
|
|
oc new-app rails-postgresql-example
|
|
|
|
to build a new example application in Ruby. Or use kubectl to deploy a simple Kubernetes application:
|
|
|
|
kubectl create deployment hello-node --image=k8s.gcr.io/e2e-test-images/agnhost:2.33 -- /agnhost serve-hostname
|
|
|
|
#+end_example
|
|
|
|
Once the namespace is created we can deploy Bitbucket using the official Bitbucket image from Atlassian.
|
|
|
|
#+begin_src bash :results output
|
|
oc new-app --image docker.io/atlassian/bitbucket-server --name bitbucket
|
|
#+end_src
|
|
|
|
#+RESULTS:
|
|
#+begin_example
|
|
--> Found container image 525a6bc (3 days old) from docker.io for "docker.io/atlassian/bitbucket-server"
|
|
|
|
,* An image stream tag will be created as "bitbucket:latest" that will track this image
|
|
|
|
--> Creating resources ...
|
|
imagestream.image.openshift.io "bitbucket" created
|
|
deployment.apps "bitbucket" created
|
|
service "bitbucket" created
|
|
--> Success
|
|
Application is not exposed. You can expose services to the outside world by executing one or more of the commands below:
|
|
'oc expose service/bitbucket'
|
|
Run 'oc status' to view your app.
|
|
#+end_example
|
|
|
|
Now, let's verify that the Bitbucket pod started successfully.
|
|
|
|
#+begin_src bash :results output
|
|
oc get pods --namespace bitbucket
|
|
|
|
#+end_src
|
|
|
|
#+RESULTS:
|
|
: NAME READY STATUS RESTARTS AGE
|
|
: bitbucket-56d9849bbf-7922z 1/1 Running 0 2m36s
|
|
|
|
As this is running successfully, let's expose it with a ~route~ so that we can access it from our web browser.
|
|
|
|
#+begin_src bash :results output
|
|
oc create route edge bitbucket --service=bitbucket --port=7990
|
|
oc get route --namespace bitbucket
|
|
#+end_src
|
|
|
|
#+RESULTS:
|
|
: route.route.openshift.io/bitbucket created
|
|
: NAME HOST/PORT PATH SERVICES PORT TERMINATION WILDCARD
|
|
: bitbucket bitbucket-bitbucket.apps.rosa-7lpn7.2pqm.p1.openshiftapps.com bitbucket 7990 edge None
|
|
|
|
Once we open the Bitbucket route in our browser, we need to follow a short setup process manually before we can continue with the rest of our automation.
|
|
|
|
1. Select your language ~English~.
|
|
2. Select ~internal~ and click ~Next~.
|
|
|
|
You'll then be prompted for an Atlassian license key. For the purposes of this workshop, we'll be generating a new trial license [[https://my.atlassian.com/license/evaluation][here]].
|
|
|
|
Copy the ~Server ID~ into the Bitbucket setup screen and click ~Generate License~.
|
|
|
|
Copy the generated license key into the text box for the Bitbucket license key and click ~Next~.
|
|
|
|
On the Bitbucket setup screen enter details for your administrative user and click ~Go to Bitbucket~.
|
|
|
|
* 3 - Configure Bitbucket
|
|
|
|
With our Bitbucket server successfully deployed, let's configure it for the workshop.
|
|
|
|
First step is to create additional users.
|
|
|
|
#+begin_src bash :results output
|
|
source .env
|
|
for user in 1 2; do
|
|
bitbucket_route=$(oc get route --namespace bitbucket | awk '{print $2}' | tail -n 1)
|
|
|
|
echo curl -v --user "admin:${bitbucket_password}" \
|
|
--request "POST" \
|
|
--location \
|
|
--header "'application/x-www-form-urlencoded'" \
|
|
--data-raw "username=user${user}&fullname=user${user}&email=user${user}%40example.com&password=${bitbucket_user_password}&confirmPassword=${bitbucket_user_password}"
|
|
https://${bitbucket_route}/rest/api/latest/admin/users?Create"
|
|
|
|
name=user${user}&password=${bitbucket_user_password}&displayName=user${user}&emailAddress=user${user}%40example.com" \
|
|
2>&1
|
|
done
|
|
#+end_src
|
|
|
