Update Docker on build container

[nathanaherne]

Description of your issue:

Docker build fails with the message Unknown Flag: chown, which is the result of having this line in the Dockerfile COPY --chown=node

If I could change the Dockerfile to separate the COPY and chown commands I would do this but the Dockerfile I am running comes from a gitub repository.

I have tried to solve this by upgrading Docker on the build image running the following commands:

build:
  ci:
    # Install pacakages to allow apt to work over HTTPS
    - 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 -
    # Add docker respositories
    - sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable edge"
    # Update package list
    - apt-get update
    - apt-get install -y docker-ce=18.05.0~ce~3-0~ubuntu

The install of Docker fails with the error

Selecting previously unselected package docker-ce.
Preparing to unpack .../docker-ce_18.05.0~ce~3-0~ubuntu_amd64.deb ...

I am sure there must be a way to update Docker on the shippable build image but I have been unable to find out how by Googling.

Hi,

Asked many times before, you can't. They said, they will push docker 18+ this month. But i didn't get updates by mail (ups, they don't do that neither). Check their blog for updates.

P.S. Blog is working with https, but docs.shippable.com only http (people, it's 2018, https is default today) ;)

@ric03uec can you please follow up on the Docker version question?

@nmarjanovic @nathanaherne we publish release notes for each release at https://github.com/Shippable/admiral/tree/master/releaseNotes We’re working on a way to let customers subscribe to them so they can get automatic updates.

@nathanaherne

• the solution that you're trying wont work because the build is running inside a docker container which means installing/upgrading docker in build steps will just install it in the container and not the host
• you could run build steps on the host using a runSh job (http://docs.shippable.com/platform/workflow/job/runsh/#yml-definition) and upgrade docker. But since docker daemon will restart after the upgrade, it'll kill shippable agent on the host which is orchestrating the build which will result in build getting stuck. So this is not recommended.

we're working on adding support for current stable docker version (18.03.x). i'll post and update on this thread once we have a specific timeline for it.

Just to put a rough ETA on this, we expect to launch Docker 18 support in the first week of August.
