set podman image storage location #1916

[//]: # kind feature

or, rather, support request.

My root is mounted at SSD for speed, and so does my home. However, I am not rich, so SSD is small, and now I want more space. First I want to move images to another disk, and if that won't help, move containers as well.

I found podman info, which printed some useful info at the end.

...
store:
  ContainerStore:
    number: 3
  GraphDriverName: vfs
  GraphOptions: []
  GraphRoot: /home/anatoli/.local/share/containers/storage
  GraphStatus: {}
  ImageStore:
    number: 1
  RunRoot: /run/user/1000/run

The path /home/anatoli/.local/share/containers/storage is 6.3G, and there is only one image 745Mb in size there.

✗ podman images -a

✗ du -hs  ~/.local/share/containers/storage
6.3G	/home/anatoli/.local/share/containers/storage

I don't see how can I move images to the other place, because vfs-images contains only meta information and vfs hosts only hash dirs.

6.3G	/home/anatoli/.local/share/containers/storage/vfs
132K	/home/anatoli/.local/share/containers/storage/vfs-containers
28K	/home/anatoli/.local/share/containers/storage/vfs-images
1.8M	/home/anatoli/.local/share/containers/storage/vfs-layers

Is there a setting that I can change to store images in a separate dir?

You can make a copy of /etc/containers/storage.conf in ~/.config/containers (this directory may need to be created first) and configure where rootless Podman stores things in that file. Be aware that, if you change these directories, it's recommended that you delete the old ones (you may end up with an unusable Podman otherwise). It sounds like you'll want to change the graph root directory, where permanent files and container images are stored. Start by changing graph driver to the rootless default (vfs) and run root to a directory in /run/user/$YOUR_UID/ (this directory does not need to exist, we'll create it if it doesn't). Then set the graph root to a location where your user has write access, and all container and image permanent files will be stored at that location.

Sounds like podman doesn't support changing image storage location with a simple user setting. Does that qualify for a future request? Having an option in ~/.config/containers/storage.conf- ImageStore.location = /data/podman-image.

mheon · 2018-12-02T16:54:42Z

We are moving over to creating the file by default, with the correct settings (so you'll only need to swap the one setting). That should be out in our next release (hopefully tomorrow). If you're looking for a way to just swap image storage, though, I don't think that's possible as of now - we storage images and containers in the same place as part of the architecture of containers/storage. We might be able to split that, but for now both must be in the same place.

abitrolly · 2018-12-03T05:01:54Z

Let me know what should I do when it is released. I guess removing podman, cleaning up config files and then reinstalling it again to create the config in my home dir? Then I will be able to edit it to set storate location.

rhatdan · 2018-12-03T19:32:57Z

SImpler fix would be to setup a bind mount
cp -R ~/.local/share/containers /data
rm -rf ~/.local/share/containers
mkdir ~/.local/share/containers
mount -o bind /data/containers ~/.local/share/containers

clebergnu · 2018-12-10T17:36:47Z

+1 for the file based configuration of the storage location.

rhatdan · 2018-12-12T15:58:38Z

With podman 0.12.1.1 It should generate ~/.lcontig/containers/storage.conf
This file can be edited to point at /data/containers.

mheon · 2018-12-12T17:17:47Z

~/.config/containers/storage.conf to be clear

mheon · 2018-12-13T14:49:01Z

It's not really clear from the generated file, but graphroot there is container and image storage

clebergnu · 2018-12-13T14:56:37Z

@mheon you're right that it's not clear... not sure if the generated ~/.config/containers/storage.conf can include comment/documentation. That alone would help a lot.

mheon · 2018-12-13T15:30:07Z

It could, but it would be a fair bit of effort on our end (straight TOML generation to templated output). Probably worth it, though.

abitrolly · 2018-12-13T15:56:54Z

Looks like Tom doesn't count comments as a feature - toml-lang/toml#284

rhatdan · 2019-03-08T15:07:08Z

@giuseppe I think your code is doing this, could you take a look.

abitrolly · 2019-03-11T06:24:39Z

How often does podman touch storage folder while sitting in a background and not starting other containers? Is there a way to measure that?

giuseppe · 2019-03-11T07:49:52Z

You'd need to change both storage.conf and libpod.conf to update the path to static dir.

Migration is currently blocked by us validating the config file settings with the db.

It should work if you start with a fresh storage

abitrolly · 2019-03-12T09:40:57Z

If migration is impossible, then the only way is remove podman, then edit files

vim $HOME/.config/containers/libpod.conf
# volume_path = "$HOME/.local/share/containers/storage/volumes"
# static_dir = "$HOME/.local/share/containers/storage/libpod"
vim $HOME/.config/containers/storage.conf
# [storage]
#   graphroot = "$HOME/.local/share/containers/storage"

, kill $HOME/.local/share/containers, and install podman again.

giuseppe · 2019-03-12T11:03:01Z

why do you need to remove podman and install it again?

rhatdan · 2019-04-13T09:42:25Z

I believe this is no longer an issue.

sunshine69 · 2021-02-27T01:35:16Z

Not sure if anything wrong with my setup as of now I seems to hit this bug. The only way to make it work is using mount bind.

as long as I have .config/containers/storage.conf with all correct settings podman always says:
Error: mkdir /var/run/containers: permission denied

podman is in fedora 33,

podman --version
podman version 2.2.1

the only thing it works by remove the custom config and then copy the storage over the other directory and empty the original one, mount bind two dir together.

Should we re-open this issue?

giuseppe · 2021-03-01T08:54:00Z

how does the .config/containers/storage.conf file look like?

locaIhost · 2021-03-04T04:32:49Z

The same situation, but tune in /etc/containers/storage.conf
and no one bothers to do symlink.

sunshine69 · 2021-03-07T08:48:49Z

how does the .config/containers/storage.conf file look like?

I have to remove it. But when I have issues described the content is as basic

[storage]
driver = "overlay"
runroot = "/mnt/portdata/containers/stevek/storage-runroot"
graphroot = "/mnt/portdata/containers/stevek/storage"
rootless_storage_path = "/mnt/portdata/containers/stevek/storage"

Well, you have many solutions

Request a list of package file from the repository.
rpm -vlq podman |grep ".conf"
Make a choice of a package dependency, go over them ;)
yum deplist podman |grep containers-common
Look it.
rpm -qdf /usr/bin/podman

Bill0412 · 2022-08-18T13:02:40Z

Thanks, this saves my life!

I don't have root permission on the machine. Solved the problem by using the following steps:

mkdir -p ~/.config/containers/
cp /etc/containers/storage.conf ~/.config/containers
Change runroot, graphroot to directories inside /run/user/$UID, you don't have to create these directories manually, podman will create them for you.
export TMPDIR="/run/user/$UID/podman-tmp", maybe you can add this to your ~/.bashrc.
mkdir -p $TMPDIR.

referenced this: #5412

YevheniiPokhvalii · 2022-09-29T00:24:07Z

My /etc/containers/storage.conf in Ubuntu WSL2 is empty.

rhatdan · 2022-09-29T10:35:13Z

Check /usr/share/containers/storage.conf

YevheniiPokhvalii · 2022-09-29T20:06:56Z

Check /usr/share/containers/storage.conf

No such file

rhatdan · 2022-09-29T20:56:39Z

Here is mine on Fedora.
storage.conf

RichardFevrier · 2022-11-22T19:29:21Z

@giuseppe can you summarize the full process with docker support please?
Let's take for example the path /var/mnt/data/containers/storage as a target.
What folders/files to create/update? (storage.conf, libpod.conf, etc...)
What should we update in those files? (driver, runroot, graphroot, rootless_storage_path, etc...)
Thank you a lot 🙏

rhatdan · 2022-11-22T20:01:34Z

It is only storage.conf, you should never do anything with libpod.conf Remove it if you have on on your system.

graphroot is used to change the system storage directories for images and containers.
rootless_storage_path will override the default location for rootless users ~/.local/share/containers/

No need to update driver or runroot.

RichardFevrier · 2022-11-23T11:53:24Z

Thanks @rhatdan
Can you update your answer (to keep it simple for anyone who's looking for a concise solution) for the case of someone already having containers. (from toolbox create, docker-compose up, etc...)
Can we simply move them? (the whole graphroot directory)
Should we recreate them?
Should we stop the systemd service(s) first? (podman-auto-update.service, podman-restart.service, podman.service, etc...)
How to check that our configuration is well applied? (sudo podman info)

YevheniiPokhvalii · 2022-11-23T19:47:10Z

If you want to copy your images from docker to podman, I was only advised this solution: #16020

docker save IMAGE | podman load

I'm not sure for containers, but I guess, you could use something like

docker export <CONTAINER ID> | podman import - some-name:latest

rhatdan · 2022-11-29T21:21:10Z

I would prefer this hack.

# docker images --format docker-daemon:{{.Repository}}:{{.Tag}} | grep -v none  | xargs podman pull

I had to create the config file: /home/user/.config/containers/storage.conf

[storage]
driver = "overlay"
#runroot = "//containers/storage-runroot"
graphroot = "//containers/storage"
#rootless_storage_path = "//containers/storage"

The two commented lines were not needed to run rootless so far.
Move the container/* files to target and then sudo systemctl restart podman and podman info to check the config was changed.
