Mantl.io Website

Build

Looking at the dependancies and configuration requirements, I decided to dockerize the deployment so we can easily host on GCE/Mantl/Wherever. The website for all it’s dynamic rendering is actually static with ZERO necessary backing stores. So multiple instances of the container can be run to scale out with ease.

There is a single build step for new code changes as follows :)

git clone [email protected]:CiscoCloud/mantl-site.git
# edit code to your hearts content
docker build .

The docker build will create you a new container with all app code and dependancies built in. You can then run this locally for testing as follows:

$ docker run -d -p 8000:80 <NEW IMAGE ID>

Then, add mantl.io to your /etc/hosts file for localhost to test with correct DNS. http://mantl.io:8000 will then provide your new preview of the site. If you get a forbidden message, you're hitting the wrong DNS name or haven't set your /etc/hosts file.

Deploy (production)

Once the container is built, we are versioning and pushing to bintray. Then using kubernetes to deploy multiple instances behind a load balancer. The Kubernetes load balancer IP has then been configured in our mantl.io cloudflare account (@matjohn2 for details) to add a cacheing and basic analytics layer in front of the site (same as the previous mantl.io site).

Tag and push the new version

Note 'v1' needs to be the a new increased integer, look at the current versions on bintray and +1.

$ docker tag 7b61ae0beb56 shippedrepos-docker-fcn-deploy-dev.bintray.io/mantlio:v1
$ docker push shippedrepos-docker-fcn-deploy-dev.bintray.io/mantlio:v1

Tell Kubernetes to do a rolling upgrade.

Use whatever your new version number from the tag operation above.

kubectl --namespace mantl-site rolling-update mantl-site --image=shippedrepos-docker-fcn-deploy-dev.bintray.io/mantlio:v2

This is currently hosted on a Google GKE cluster. We can easily put this wherever in future if a move is needed.
