Helm

Description​

Helm is a package manager for Kubernetes. It is a tool that streamlines installing and managing Kubernetes applications. Think of it like apt/yum/homebrew for Kubernetes.

Installation​

  1. Adding Helm GPG Key to Keyrings

    curl -fsSL https://packages.buildkite.com/helm-linux/helm-debian/gpgkey | gpg --dearmor | sudo tee /usr/share/keyrings/helm.gpg > /dev/null
    • curl -fsSL https://packages.buildkite.com/helm-linux/helm-debian/gpgkey: Downloads the Helm signing key from Buildkite using curl.
    • | gpg --dearmor: Pipes the downloaded key into gpg to convert the ASCII key into a binary format.
    • | sudo tee /usr/share/keyrings/helm.gpg > /dev/null: Writes the binary key to /usr/share/keyrings/helm.gpg, effectively adding the Helm keyring to the system's list of trusted keys. > /dev/null sends any output messages to a null device, suppressing them from appearing in the terminal.

  2. Install Transport over HTTPS

    sudo apt install apt-transport-https --yes
    • sudo apt install apt-transport-https --yes: Ensures that the package apt-transport-https is installed, which is required for apt to retrieve packages over HTTPS. The --yes flag automatically confirms the installation without user interaction.

  3. Adding Helm Repository to Sources List

    echo "deb [signed-by=/usr/share/keyrings/helm.gpg] https://packages.buildkite.com/helm-linux/helm-debian/any/ any main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list
    • echo "deb [signed-by=/usr/share/keyrings/helm.gpg] https://packages.buildkite.com/helm-linux/helm-debian/any/ any main": Constructs a new source list entry signed by the previously added Helm GPG key.
    • | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list: Writes the new source list entry to /etc/apt/sources.list.d/helm-stable-debian.list, making the Helm repository available to apt.

  4. Updating Package List

    sudo apt update
    • sudo apt update: Updates the local package index to include the new Helm repository, ensuring that apt is aware of the latest packages available for installation.

  5. Installing Helm

    sudo apt install helm
    • sudo apt install helm: Installs Helm using apt, now that the package index has been updated to include Helm's repository.

These steps collectively configure the system to recognize the Helm package repository and ultimately install Helm using the system's package manager.
