+[Kontemplate](https://github.com/tazjin/kontemplate) is lighter and easier than Helm, which makes it a good alternative for projects that do not require a more complex solution. It is a simple CLI tool that can take sets of Kubernetes resource files with placeholders and insert values per environment. It works with standard Kubernetes YAML and/or JSON manifest files with templating instructions in a format based on Go's templating engine. It also has some interesting features like integration with kubectl (e.g. the --dry-run flag) and [pass](https://www.passwordstore.org), which makes it work well with CI pipelines.
