Error on docker-ce install, installed docker-ce package post-installation script subprocess returned error exit status 1

I tried to install docker-ce on ubuntu cloud image. I followed steps on readme file provided by ubuntu template and using ubuntu-cloudimg.pkr.hcl.

I found this error:

    cloudimg.image.qemu.cloudimg: Job for docker.service failed because the control process exited with error code.
    cloudimg.image.qemu.cloudimg: See "systemctl status docker.service" and "journalctl -xe" for details.

Here are my system information

Distributor ID:	Ubuntu
Description:	Ubuntu 22.04.2 LTS
Release:	22.04
Codename:	jammy

After some try and error using solution provided on:

1. Docker Engine does not start on Ubuntu 22.04 due to iptables issues  docker/for-linux#1437
2. https://forums.docker.com/t/ubuntu-22-04-and-5-23-0-0-1-now-fails-to-start-please-suggest-debug/134472
3. Deinstall and install of docker ce fails on ubuntu 18.04 moby/moby#41792

I fixed it with this steps:

1. I make custom script in custom-script.sh. It is using separated install steps like on this discussion, and install using iptables legacy like on this

sudo rm -rf /var/lib/docker /etc/docker
sudo rm /etc/apparmor.d/docker
sudo groupdel docker
sudo rm -rf /var/run/docker.sock
sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common lsb-release
lsb_release -a
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add
sudo add-apt-repository 'deb [arch=amd64] https://download.docker.com/linux/ubuntu jammy stable'
update-alternatives --set iptables /usr/sbin/iptables-legacy
update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
sudo apt-get update
sudo apt-cache show docker-ce
sudo apt-get install -y containerd.io
sudo apt-get install -y docker-ce-cli
sudo apt-get install -y docker-ce
echo $USER
sudo usermod -aG docker $USER

2. I update the setup-boot.sh to not delete the kernel, instead i delete the kernel after the docker process installation done using new script i created in clear-kernel.sh.

# setup-boot.sh
packer_apt_proxy_config="/etc/apt/apt.conf.d/packer-proxy.conf"
if  [ ! -z  "${http_proxy}" ]; then
  echo "Acquire::http::Proxy \"${http_proxy}\";" >> ${packer_apt_proxy_config}
fi
if  [ ! -z  "${https_proxy}" ]; then
  echo "Acquire::https::Proxy \"${https_proxy}\";" >> ${packer_apt_proxy_config}
fi

cloud-init clean --logs

# The cloud image for qemu has a kernel already. Remove it, since the user
# should either install a kernel in the customize script, or let MAAS install
# the right kernel when deploying.
apt-get remove --purge -y linux-virtual 'linux-image-*'
apt-get autoremove --purge -yq
apt-get clean -yq

3. I update theubuntu-cloudimg.pkr.hcl to run above scripts in order.

# truncated
build {
  name    = "cloudimg.image"
  sources = ["source.qemu.cloudimg"]

  provisioner "shell" {
    environment_vars = concat(local.proxy_env, ["DEBIAN_FRONTEND=noninteractive"])
    scripts          = ["${path.root}/scripts/cloudimg/setup-boot.sh"]
  }


  provisioner "shell" {
    environment_vars  = local.proxy_env
    expect_disconnect = true
    scripts           = ["${var.customize_script}"]
  }

  provisioner "shell" {
    environment_vars = concat(local.proxy_env, ["DEBIAN_FRONTEND=noninteractive"])
    scripts          = ["${path.root}/scripts/cloudimg/clean-kernel.sh"]
  }

# rest of file template

I am new on this tools, Packer and MAAS. I just want to know if this is a right step or if have any drawback.

Thanks.

I can't say whether this is the best fix for the Docker issue, but from the Packer/MAAS standpoint the way you implemented it is perfectly fine.

After checking again several times, it doesn't need legacy iptable and separated install step. I think it only needs kernel during installation. Here is the updated script, hope it helps:

sudo apt-get install -y apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add
sudo add-apt-repository 'deb [arch=amd64] https://download.docker.com/linux/ubuntu jammy stable'
sudo apt-get update
sudo apt-cache show docker-ce
sudo apt-get install -y containerd.io docker-ce-cli docker-ce
echo $USER
sudo usermod -aG docker $USER
