Prerequisites

The following imagestreams should be installed on OpenShift:

oc login -u system:admin
oc create -n openshift -f https://raw.githubusercontent.com/jboss-fuse/application-templates/master/fis-image-streams.json
oc create -n openshift -f https://raw.githubusercontent.com/jboss-openshift/application-templates/ose-v1.4.14/eap/eap64-image-stream.json
oc create -n openshift -f https://raw.githubusercontent.com/jboss-openshift/application-templates/ose-v1.4.14/openjdk/openjdk18-image-stream.json
oc create -n openshift -f https://raw.githubusercontent.com/jboss-openshift/application-templates/ose-v1.4.14/processserver/processserver64-image-stream.json
oc create -n openshift -f https://raw.githubusercontent.com/jboss-openshift/application-templates/ose-v1.4.14/webserver/jws31-tomcat8-image-stream.json
oc create -n openshift -f https://raw.githubusercontent.com/jboss-openshift/application-templates/ose-v1.4.14/eap/eap70-image-stream.json
oc create -n openshift -f https://raw.githubusercontent.com/jboss-openshift/application-templates/ose-v1.4.14/decisionserver/decisionserver64-image-stream.json
oc create -n openshift -f https://raw.githubusercontent.com/jboss-openshift/application-templates/ose-v1.4.14/datagrid/datagrid65-image-stream.json

Run Playbooks Locally (Ansible installed)

$ git clone https://github.com/siamaksade/openshift-demos-ansible.git
$ cd openshift-demos-ansible
$ git checkout ocp-3.10
$ oc login http://openshiftmaster
$ ansible-galaxy install -r playbooks/coolstore/requirements.yml
$ ansible-playbook playbooks/coolstore/msa-cicd-eap-min.yml

Run Playbooks Locally (Docker installed)

  • Install Docker
  • Run the playbooks
$ oc login http://openshiftmaster
$ docker run --rm -it siamaksade/openshift-demos-ansible:ocp-3.10 playbooks/coolstore/msa-cicd-eap-min.yml \
      -e "openshift_master=$(oc whoami --show-server)" \
      -e "oc_token=$(oc whoami -t)"

Run Playbooks on OpenShift (with cluster admin)

The provided templates creates an OpenShift Job to run the Ansible playbooks. Check out the template for the complete list of parameters available.

$ oc login -u system:admin
$ oc new-project demo-installer
$ oc adm policy add-cluster-role-to-user cluster-admin system:serviceaccount:demo-installer:default

$ oc new-app -f helpers/coolstore-ansible-installer.yaml \
    --param=DEMO_NAME=msa-full \
    --param=PROJECT_ADMIN=developer \
    --param=COOLSTORE_GITHUB_REF=ocp-3.10
    --param=ANSIBLE_PLAYBOOKS_VERSION=ocp-3.10

$ oc logs -f jobs/coolstore-ansible-installer
