Deploying IBM MQ with a single command

Introduction

In a previous blog (https://medium.com/ibm-garage/deploying-ibm-app-connect-with-a-single-command-fc02e4887228), I described how to deploy IBM App Connect with a single command.

Well, AppConnect is part of Cloud Pak for Integration, which has other components.

In this blog, I will describe how to deploy IBM MQ, another component of the same Cloud Pak, then I will tell you to do the same with a single command.

Step-by-Step Deployment

I assume you have deployed Cloud Pak for Integration in your OpenShift cluster, and now you want to deploy an instance of IBM MQ. Follow these steps to deploy:

Define the following environment variables:

export NAME=<name-of-mq-instance>
export PROJECT=mq
export SCC=ibm-anyuid-hostpath-scc
export IMAGE_SECRET=prod-secret
export TLS_SECRET=ibm-mq-tls-secret
export ICP_PASSWORD=<icp-password>

Obtain the ICP Console route:

export MASTER_URL=$(oc get route icp-console -n kube-system -o jsonpath='{@.status.ingress[0].host}')

Configure the Helm CLI:

cloudctl login -a $MASTER_URL -u admin -p $ICP_PASSWORD -n kube-system --skip-ssl-validation

Create the MQ project:

oc new-project $PROJECT

Associate the OpenShift Security Context Constraint to the project service account:

oc adm policy add-scc-to-group $SCC system:serviceaccounts:$PROJECT

Create the TLS Secret, using the certificates stored in the Helm directory:

oc create secret generic $TLS_SECRET \
--from-file=tls.crt=$HOME/.helm/cert.pem \
--from-file=ca.crt=$HOME/.helm/ca.pem \
--from-file=tls.key=$HOME/.helm/key.pem

As we are using the IBM Container Registry to pull the container images, we need to set the image pull secret.

Assuming you have a valid entitlement key, we need to fetch the key first.

The good news is that there is a github repository with a script that shows the key.

So, run the following commands to download the script and add to your path:

curl https://raw.github.ibm.com/CloudPakOpenContent/cloudpak-entitlement/master/pak-entitlement.sh?token=AAAslythPohyzFwjlgwEmZFFna3_T2K4ks5d3-uwwA%3D%3D > pak-entitlement.sh
chmod a+x ./pak-entitlement.sh
sudo mv ./pak-entitlement.sh /usr/local/bin

Now run the following script to set the entitlement key:

ENTITLEMENT_KEY=$(pak-entitlement.sh show-key Integration)
echo Key: $ENTITLEMENT_KEY

Create the image pull secret:

oc create secret docker-registry $IMAGE_SECRET \
--docker-server=cp.icr.io --docker-username=ekey \
--docker-password=$ENTITLEMENT_KEY

Finally, install the IBM MQ, using the Helm chart:

helm install https://github.com/IBM/charts/blob/master/repo/entitled/ibm-mqadvanced-server-integration-prod-4.1.0.tgz?raw=true \
--name $NAME --tls --set image.pullSecret=$IMAGE_SECRET \
--set license="accept"

This is pretty cool, but lot’s of commands and copy-and-paste.

Let’s describe a better way.

Deploying IBM MQ with a single command

I wrapped all these commands in a nice script. The first thing you need to do is to clone the Github repository:

git clone https://github.com/patrocinio/cloud-paks-resilience
cd cloud-paks-resilience/Integration

Now, just run the following command:

./deploy_mq <mq-name>

And you’ll see the Helm release output:

Eduardos-MBP:Integration edu$ ./deploy_mq.sh my-mq2[...]NOTES:Get the MQ Console URL by running these commands:export CONSOLE_PORT=$(kubectl get services my-mq2-ibm-mq -n mq -o jsonpath="{.spec.ports[?(@.port=="9443")].nodePort}")export CONSOLE_IP=$(kubectl get configmap ibmcloud-cluster-info -n kube-public -o jsonpath="{.data.proxy_address}")echo https://$CONSOLE_IP:$CONSOLE_PORT/ibmmq/consoleGet the MQ connection information for clients outside the cluster by running these commands:export MQ_PORT=$(kubectl get services my-mq2-ibm-mq -n mq -o jsonpath="{.spec.ports[?(@.port=="1414")].nodePort}")export MQ_IP=$(kubectl get configmap ibmcloud-cluster-info -n kube-public -o jsonpath="{.data.proxy_address}")echo $MQ_IP:$MQ_PORTThe MQ connection information for clients inside the cluster is as follows:my-mq2-ibm-mq.mq.svc:1414

Conclusion

In this blog, I showed how to deploy IBM MQ using a sequence of commands, then using a single script.

Now, you can deploy IBM MQ with a single command!
