<p>I'm currently using Ansible to template out Helm values files and deploy Helm charts to Kubernetes. However, this happens in sequence and generally takes a long time to deploy because of the number of Helm charts needed to deploy. I'm looking for a way to deploy Helm charts in parallel.</p>
<p>A few of my Helm charts depend on each other, but many of the charts could be deployed in parallel. There are also instances where I want to conditionally decide to deploy a Helm chart before another chart. For example, sometimes (but not always) I want to run a database migration Helm chart to completion before running an application helm chart. Also, sometimes, I want to deploy the entire suite of Helm charts all at once and sometimes I just want to deploy a particular chart or subset of charts without impacting other deployed charts.</p>
<p>I was wondering if there are any projects or tooling around deploying Helm charts in parallel, while setting dependencies and conditionals.</p>
<p>I've encountered the Helmfile project, which looks interesting. However, it's not clear to me if this project supports parallel execution and dependent execution.</p>
<p>Has anyone encountered a similar need and found a tool that works for conditionally deploying Helm charts in parallel? Or has anyone leveraged Helmfile to achieve this?</p>

<p>I use Helmfile for my projects. While I don't use the <code>--concurrency</code> flag, because my charts are specifically ordered, helmfile is VERY powerful. It seems from the githubs people use <code>bases:</code> in helmfile to establish their parallel charts, and everything that is ordered in the releases.</p>
<p>Also if your individual charts have dependencies, you can specify those in the <code>chart.yaml</code> to simplify your releases and then just do everything in parallel without further complicating the helmfile project.</p>
