Use Gitpod installer from Docker

gitpod-installer.sh

#!/bin/bash

# Save this script to a `gitpod-installer` file, make it
# executable and save to your $PATH directory. Now you can
# use this as you would the normal Installer binary.
#
# To change the Installer version, apply a `GITPOD_INSTALLER_VERSION`
# environment variable (or change the default value).

set -euo pipefail

# Set the version to use - see https://werft.gitpod-dev.com for available values
GITPOD_INSTALLER_VERSION="${GITPOD_INSTALLER_VERSION:-release-2022.01.12}"

# Check docker is available
which docker > /dev/null || (echo "Docker not installed - see https://docs.docker.com/engine/install" && exit 1)

# Now, run the Installer
docker run -it --rm \
    -v="${HOME}/.kube:${HOME}/.kube" \
    -v="${PWD}:${PWD}" \
    -w="${PWD}" \
    "eu.gcr.io/gitpod-core-dev/build/installer:${GITPOD_INSTALLER_VERSION}" \
    "${@}"
