Questions tagged [helm3]

Version 3 is the only currently-supported version of the Kubernetes Helm deployment tool. Use [kubernetes-helm] instead of this tag.

The tool deploys applications as "charts" of templated YAML files. Version 3 of Helm was released on November 13, 2019; version 2 became unsupported a year later, on November 13, 2020.

There are only minor differences in the templating engine between the two versions. The major differences are operational: Helm 3 no longer requires an in-cluster "Tiller" management tool, and its command-line options are different for some common commands. Questions about migrating Helm 2 to Helm 3 or other non-programming questions are not generally on-topic for Stack Overflow, and might be better asked on related sites like Server Fault or DevOps.SE.

Questions with this tag should almost always be tagged with , and often with either or both of and , depending on the specifics of the question. However, since the Helm 3 is the only currently supported version and since template language has remained essentially the same between the two versions, it is not usually necessary to tag a question as .
