It's fairly common that you need to expose a lot of env variables to a pod, like this: I literally have containers with 40 of these, which means a lot of boilerplate repeating the stanza over and over. To store a Helm chart, first of all you need to import the shared configuration that defines the integrated Helm Repository. To do this I'm going to walk through an example where at the beginning we install helm charts over the CLI using the helm command, and then refactor the code in steps to use the helmfile command instead. Using override values is currently the only way to pass down environment variables to the chart. answers Stack Overflow for Teams Where developers technologists share private knowledge with coworkers Jobs Programming related technical career opportunities Talent Recruit tech talent build your employer brand Advertising Reach developers technologists worldwide About the company Log Sign.
