Theory:

Helm Commands:

• helm repo: interact with charts repository. Helm-3 no longer ships with a default chart repository

  • helm repo list
  • helm repo add <name> <url>
  • helm repo remove <name>

• helm search: for finding charts for e.g. helm search repo <chart>

• helm show: information about a chart

  for e.g. helm show <values|chart|readme|all><chart-name>

• helm install: Install a package

  for e.g → helm install <release-name><chart-name>

  • wait until all subjects are ready

    for e.g.

    • helm install mychart stable/tomcat --wait --timeout 10S

• helm create: create a new chart with given name

  for e.g → helm create <chart-name>

⇒ there are two ways to pass configuration data during install

• --set: specify overrides on the command line

• --values: specify a YAML file with overrides

  (or -f)

  for e.g-

  • helm install mychart stable/tomcat --set servicetype=nodeport
  • helm install testchart stable/jenkins --set master servicetype=nodeport // Nodeport is Load balancer //

• helm get: information about from a named release

  • helm get <all|manifest|values><release_name>

    for e.g → helm get all mychart

• helm list: list all the named releases

• helm status: display the status of the named release

  for e.g. → helm status <release_name>

  e.g - helm status mychart

• helm pull: download a chart form a repository

  • helm pull <chartname> #download the tar

  • helm pull --untar <chartname> #download and untart

    e.g: helm pull --untar stable/tomcat

• install from a local chart archive

  e.g: helm install mychart tomcat-0.4.3.tgz

• install from an unpacked chart directory:

  e.g: helm install mychart

• install from a full URL

  e.g: helm install mychart <URL>
