podman commit on containers with a large files throws error: io: read/write on closed pipe

Rubusch commented 4 days ago

Issue Description

My original motivation is creating dockerized development environments keeping installations of Xilinx Vivado and tooling. This Package is huge ~100GBs+. Migrating this setup from docker-compose/docker to podman, I saw this problem using podman build. Manually I tried to stop building at half of the image, then login to the container, and install Vivado manually which worked. Outside then I tried a commit of the container, (to my understanding this is what a RUN instruction in a Dockerfile is performing). This produced the exact same error: ...:io: read/write on closed pipe.

I found a similarly described issue here: 8845. But my case seems to be different: In the issue huge files are copied into the container. In my case the container contains a huge file and I'd like to commit it (assumed it is my issue with installing Vivado). Anyway I also tried to play with systemd notification w/o success here. As mentioned, the setup worked actually with docker, so I assume a bug here. Thus, here to reproduce what probably provokes my error is the described approach down below.

If there is anything I missed out which makes this setup work, pls don't hesitate to let me know! Perhaps I'm wrong with my assumption and the commit. Also, I highly appreciate any hints to make this run.

Steps to reproduce the issue

Steps to reproduce the issue
(this is the 'sudo' version to rule out permission related things, but rootless shows the same result):

Create Dockerfile with:
```
FROM alpine:3.1
```
Execute sudo podman build -t test-large-container.

Run the container and login, then create a "huge file"

$ sudo podman run --rm -it localhost/test-large-container /bin/sh
/ # dd if=/dev/zero of=large-file-1gb.txt count=102400 bs=1048576

In a different shell, try to commit:

$ sudo podman commit 529e4d221b0c localhost/test-large-container

Describe the results you received

I receive the described error:

Can't add file /var/lib/containers/storage/overlay/.../large-file-1gb.txt to tar: io: read/write on closed pipe

Describe the results you expected

Doing the Steps to reproduce the issue with 10GB works. The same I would expect for >100G.

Any chance you could try this with a newer podman version 5.*

Rubusch commented 4 days ago

I would like to. I tried downloading podman-remote-static-linux_amd64.tar.gz 5.1.1 but was not sure how to use it. After unpacking I simply placed it at /usr/bin/podman. Then - following https://podman.io/docs/installation somehow - I tried podman machine init, followed by podman machine start. I received an error, the old .sock file was there, no connection. (Feeling lucky) I simply removed the .sock. Then it complained about gvproxy not being there or /and I should register some dns at [engline] in the container.conf. I felt a bit in the weeds and gave that up. Is there something I can do to stop the existing podman, and replace it by this statically linked version?

That is probably not what you wanted to do. Getting an updated version of Podman onto Ubuntu is a bit painful, which is why I use Fedora...
