are you using remote docker at all?

I don't know: what is remote docker? I do build docker images on circleci

building docker images requires a VM under the hood, there’s 2 ways to do this: via machine executor, or via the setup_remote_docker step in the docker executor. The latter spins up a remote VM and connects you to the docker socket

the setup_remote_docker step has an optional version number - and defaults to a very old version

@glenjamin Hmm yes, I have this in my clj-kondo config:

docker:
    docker:
      - image: circleci/buildpack-deps:stretch
    steps:
      - checkout
      - setup_remote_docker
      - run:
          name: Build Docker image
          command: .circleci/script/docker

I set this up about 1.5 year ago. What's the best way to do this now? I don't have a preference

- setup_remote_docker
    version: 19.03.12    

why not just bump the defaults yourself at circleci?

because that’s not backwards compatible 😞

we might still do it later, and we might do it only for new projects

but mainly we want people to select a version they’re happy with

some people prefer a fixed version, some prefer “gimme latest”, and we don’t know who is who

can I also fill in: version: latest, so it'll always use the latest and I never have to think about it again? :)

you currently cannot, but i just mentioned that to the machine images team

in general that’s problematic, because when we change it some percentage of builds break and we get a bunch of support tickets

thanks so much, I'll just change it to the version you mentioned

oh, 19.03.13 is out now too if you want to use the latest-latest

I'll do that in a year or two when I get another email :)

just bumped them

good to know 🤔 I received this email as well

the team which sent it is iterating on the copy in the discuss post, but annoyingly emails are static 😄

link?

https://discuss.circleci.com/t/old-linux-machine-image-remote-docker-deprecation/37572

Idea for future emails: include link to pre-created discuss thread :)

Thanks for sharing

I've got this in my config:

docker:
    docker:
      - image: circleci/buildpack-deps:stretch
    steps:
      - checkout
      - setup_remote_docker:
          version: 19.03.12
      - run:
          name: Build Docker image
          command: .circleci/script/docker

Yet I see

Build-agent version 1.0.40344-226c2ebb (2020-10-01T12:44:53+0000)
Docker Engine Version: 18.09.6

oh I see, the third step has a remote docker

never mind then
