Please add support for Podman OCI #829
Description
Is there an existing issue for this?
- I have searched existing issues, it hasn't been reported yet
Use case description
When we tried running the Serverless-python-requirments plugin with Podman OCI runtime we are unable to build the pythonrequirments.zip
Getting the below error when I tried running the below command
sls requirements install
Environment: darwin, node 20.5.1, framework 3.34.0 (local) 3.34.0v (global), plugin 6.2.3, SDK 4.3.2
Docs: docs.serverless.com
Support: forum.serverless.com
Bugs: github.com/serverless/serverless/issues
Error:
Error: spawn docker ENOENT

at onErrorNT (node:internal/child_process:484:16)
at process.processTicksAndRejections (node:internal/process/task_queues:82:21)
Tried modifying directly in the docker.js with command as podman instead of docker in
async function dockerCommand(options, pluginInstance) {
const cmd = 'Podman';

Hey @schinnaswamy 👋 Thanks for reporting and sorry you've run into trouble. Is
podmanCLI compatible withdockerCLI? Did you try aliasing locallypodmantodocker? Plugin usesdockerpretty transparently, so as long as the API is the same, it should work just fine, I'm not usingpodmanpersonally so it's hard for me to verify at the moment.schinnaswamy commentedon Feb 26, 2024
@pgrzesik
Thanks for looking at the issue.
Yes I tried aliasing Podman to docker. But after making couple of modifications in the following .js files and removing :z from bind path syntax in the docker run command since Podman has some issues with extended attribute was getting error
lsetxattr /: operation not supportedStep 1:
alias docker=podmanEven though I have added alias but still for some reason the command was trying to connect to the docker daemon via API.
So I have to modify explicitly the following js files in the serverless-python-requirements
Step 2 : Modified docker.js Line No : 13.
const cmd = 'podman';Step 3: Modified pip.js Line No: 269 & 371 & 416
dockerCmd.push('podman', 'run', '--rm', '-v',${bindPath}:/var/task);case 'podman':if (cmd === 'podman' && e.stderrBuffer) {Step 4: Removed :z in the pip.js file [ Line No: 269, 278, 280, 282 & 311 ]
With the above following modifications managed to run the serverless deploy with Python requirements without any issues.

Hey @schinnaswamy - thanks a lot for more details. That's interesting that the compatibility doesn't seem to be universal, at least in case of use via the plugin. I will try to find some time to run it myself via
podman, but I cannot promise anything concrete right now. I would like to avoid having specific code modifications forpodmanif possible to reduce complexity on plugin sideconnorhsm commentedon Jul 10, 2024
Also experiencing this, found a simpler workaround is to symlink docker to Podman.
sudo ln -s /opt/homebrew/bin/podman /usr/local/bin/docker
