Helm: Installing Helm on Ubuntu

Update Aug 2023: using newer ‘signed-by’ attribute for apt signing keys.

Installing Helm using apt is a straight-forward procedure and documented on the official site.  Coming straight from the official helm documentation, here are the commands for Ubuntu 22.

curl https://baltocdn.com/helm/signing.asc | gpg --dearmor | sudo tee /usr/share/keyrings/helm.gpg > /dev/null
sudo chmod 644 /usr/share/keyrings/helm.gpg
sudo apt install apt-transport-https --yes
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/helm.gpg] https://baltocdn.com/helm/stable/debian/ all main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list
sudo apt update
sudo apt install helm -y

Check the version and available helm repositories using:

# check version
helm version

# available helm repo
helm repo list

Helm3 alias

For historical reasons, you may want ‘helm3’ to alias this same version.  This can be done using the Debian/Ubuntu alternatives concept, but also with a simple link.

Alternatives concept (preferred)

sudo update-alternatives --install /usr/local/bin/helm3 helm3 /usr/sbin/helm 20
sudo update-alternatives --query helm3
ls -l /usr/local/bin/helm3
helm3 version

Link

sudo ln -s /usr/sbin/helm /usr/local/bin/helm3
helm3 version
