The helm-manger is possible to run as a docker container. However, a local kubernetes must be running where the application can be installed.

This instruction is valid for running both in a local kubernetes and in a kubernetes ccluster

If running in a local kubernetes, set the env KUBE_HOST to localhostCreate a private docker network, unless it already exists, for the containers to run in.

If running in a kubernetes cluster, set the env KUBE_HOST to the ip of the clusterStart the chartmuseum container in a separate window. This will be used as a chart repository. Make note of the port, 8222, which will be available on local host. Charts uploaded to the chartmuseum container will be availed in the mounted dir 'charts' on your host.
