Automating Helm deployments with Bash

Some of our applications are hosted in a Kubernetes cluster, and we use GitLab Continuous Integration (CI) to automate deployments and Helm 2 to deploy our applications. Helm charts enable the storage of templates of Kubernetes object YAML files with variables that can be programmatically set from command-line arguments passed when the chart is used during deployments. This allows us to store critical secrets in GitLab-protected environment variables or in Hashicorp Vault and use them within the CI deployment job.
