Let‘s Connect 2022 October 26, 2022 Things we learned, improved, simplified going to container- based delivery with Connections Cameron Bosnic, HCLTech @CameronBosnic 

Let’s Connect 2022 October 26, 2022 Agenda • Install upgrade types • CNX8 and beyond delivery model • Harbor • Infrastructure upgrades and migrations • Ansible deployment scripts • Update with cron or Jenkins • Upgrade component with ansible 

Let’s Connect 2022 October 26, 2022 Upgrade Types • In place • Easiest option for smaller environments • Run the Installation Manager to upgrade the Connections server. Helm upgrade command to install/upgrade the Component Pack. • Side by Side • Most used technique, used by technical advisors • New 'clean' install • Stage changes and config and switch over when the configuration and customizations look good • Hybrid • Hybrid upgrade uses the same process as in-place, a new environment identical to production • Can still test customizations as with a side by side upgrade 

Let’s Connect 2022 October 26, 2022 Upgrade Types • Component pack delivered as huge zip file • Deliveries have been slow (annual) • All images and charts require setting up internal registry • Each image individually added to registry • Not taking advantage of some of the strengths of containers 

Let’s Connect 2022 October 26, 2022 CNX 8 + Delivery Model • Continuous quarterly releases • Regular feature releases, bug fixes, and security updates • Enabled by Harbor • Automatable with Ansible • Quarterly release cadence on both WebSphere and Kubernetes side • K8s kept up to date (most recent 3 releases) 

Let’s Connect 2022 October 26, 2022 CNX 8 + Delivery Model 

Let’s Connect 2022 October 26, 2022 Harbor • Harbor is a repository for our Component Pack build containing: • Charts • Helm 3 • Images • Docker images • for components 

Let’s Connect 2022 October 26, 2022 Harbor • Access: Register for Harbor and get username/token at hclr.io Entitlement and access to repo added by Harbor team • Deploy: Change Helm repo with helm repo add (Demo) Helm upgrade … (Demo) 

Let’s Connect 2022 October 26, 2022 CNX Infrastructure Upgrades and Migrations Recreate Ingress (for upgrade to cnx8 once only) • Ingresses have been moved to their respective component Helm charts and need to be recreated kubectl delete ingress -n connections $(kubectl get ingress -n connections | awk '{print $1}' | grep -vE "NAME") helm upgrade cnx-ingress -i ingress-nginx/ingress-nginx --namespace connections - f cnx-ingress-values.yml --wait 

Let’s Connect 2022 October 26, 2022 CNX Infrastructure Upgrades and Migrations Mongo3 -> Mongo5 • Pull Mongo Dockerfile from github, build image • Import to containerd in worker nodes, update Helm chart to pull the image • Export from Mongo3 • Import to Mongo5 

Let’s Connect 2022 October 26, 2022 CNX Infrastructure Upgrades and Migrations Elasticsearch -> OpenSearch • Export from ElasticSearch7 • Import to OpenSearch 

Let’s Connect 2022 October 26, 2022 Ansible Deployment Scripts Public Git repo: https://github.com/HCL-TECH-SOFTWARE/connections- automation Used daily to install / upgrade our internal deployments. Available as a public Git repo as a proof of concept for our customers to get an idea how to automate the process and with the possibility to extend upon it. Install configurations are driven by a set of inventory files tailored to the system being deployed. Install actions are driven by a set of playbooks to deploy different parts of the products.
