Unsupported distribution 'ol '

Hello everyone

I'm trying to install docker on my Linux 7.8 with the Docker Installation Scripts provided here, i.e.

curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh

But the command return the error message:

Executing docker install script, commit:442e66405c304fa92af8aadaa1d9b31bf4b0ad94
ERROR: Unsupported distribution 'ol'

The 'ol' mentioned in the error message is as same as the ID value of my OS.

[root@linux7-8instance ~]# cat /etc/release

Could you tell me what's wrong here?

Thank you

Oracle Linux is unsupported on Docker CE, but probably you can use CentOS RPMs: https://download.docker.com/linux/centos/7/x86_64/stable/Packages/

Why is it unsupported? probably can use centos rpm's as the system is fully compatible, so what is the problem with CE ?

Did you solve this? I wanted to update Docker and getting the same error. And I'm running on Oracle too.

Hi man I looked on the web for some guide and installed it. I am not 100% sure if this was the one but I think so:

I think we may use the "ID_LIKE" field instead of the "ID" to check if the base OS is supported. So I created a pull request for this change: #231

This pull request is tested on pardus and its working perfectly.

================================================================================

To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:

    dockerd-rootless-setuptool.sh install

Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.


To run the Docker daemon as a fully privileged service, but granting non-root
users access, refer to https://docs.docker.com/go/daemon-access/

WARNING: Access to the remote API on a privileged Docker daemon is equivalent
         to root access on the host. Refer to the 'Docker daemon attack surface'
         documentation for details: https://docs.docker.com/go/attack-surface/

================================================================================

I have installed docker on more than 500 servers running Pardus this way and they are working perfectly for more than 6 months.

If you think this change is risky than you may consider adding an option (for example --support-base-os) to use the "ID_LIKE" field so the user may take the risk himself.

Yes, we don't provide packages for Oracle Linux; as mentioned above, it's possible that packages for other similar distros work, but we don't want to update the script to automatically "guess" something that "could" work, because no testing/verification is done on those distros, and we try to avoid "pretending" that it's supported / tested. Also see https://docs.docker.com/engine/install/#other-linux-distros

My general recommendation would be to;

• Verify if the packages work for your situation / distro (in a testing environment)
• If they do, and you're comfortable running them on your systems, and if you need to automate setups; create a script based on the steps of this script;
  • you can use --dry-run to see the steps it executes
  • or (as the script largely automates the manual installation steps); base your script on the instructions for the distro you're installing packages for; e.g. https://docs.docker.com/engine/install/centos/

Maybe (to be discussed) we could consider a manual "I know what I'm doing" option that allows overriding these options (e.g. as suggested in #229, or a --override-distro=xxx flag), but that needs to be discussed.

I'm closing this ticket for now, but feel free to continue the conversation or to open a ticket with a proposal for alternatives.
