@IRCody IRCody commented Feb 17, 2021

This changed based on feedback on the PR to use a different method. I kept the previous description for clarity below.

What is this

This PR adds the ability to tag namespaces with a special label, containerd.io/namespace/sharable that indicates that images in this namespace are shareable with other namespaces.

Why is this

The goal is to be able to have namespace isolation while being able to share some common content across all namespaces.


What is this

This PR adds a 'shared' namespace setting that enables content to be shared from a single, configured namespace when content_sharing_policy is set to isolated. It does this by looking for content first in the calling namespace and then, if configured, in the 'shared' namespace.

The config looks like:

[plugins.bolt]
content_sharing_policy = "isolated"
shared_content_namespace = "<shared_namespace>"

In other respects the 'shared' namespace is unmodified. Pulling content into a 'shared' namespace is no different from any other namespace for example.

This intentionally tries to not modify behavior in the default case. There should be no change except in the case that shared_content_namespace is set explicitly.

Why is this

The goal is to be able to have namespace isolation while being able to share some common content across all namespaces.

Example workflow

Add a config.toml snippet like:

...
[plugins.bolt]
content_sharing_policy = "isolated"
shared_content_namespace = "shared"
...

After starting containerd with this config, pull an image into the shared namespace:

ctr -n shared image pull docker.io/library/busybox:latest

Then check that there is nothing in the target namespace called empty:

ctr -n empty image ls

Now run it busybox in the empty namespace:

% ctr -n empty run docker.io/library/busybox:latest busybusy /bin/sh

Exit the busybox container and verify that the empty namespace does not have image present after running:

% sudo ctr -n empty image ls

Open questions

  • Are changes needed to leases or gc? I'm less sure about this and will try to look into the code for a bit more to try to be sure I understand implications.

Hi @IRCody. Thanks for your PR.

I'm waiting for a containerd member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

It should be possible to support this through a property on the actual namespace. Having another hard code special namespace is not ideal from my perspective. You could have a content policy which allows the namespace to set a shared content label.

The shared namespace in this PR is not hardcoded but is configurable. I'm very open to other ways to accomplish the same thing here though, which is limited sharing of content from a single namespace with other namespaces while the content sharing policy remains isolated.

You could have a content policy which allows the namespace to set a shared content label.

I'm not sure I completely understand what you mean here (sorry, I might be missing something). Are you saying instead of checking for this value of a shared namespace if the content is not found in the current namespace it would instead check the labels of the given namespace, which would contain info telling it what other namespace(s) have shared content with the namespace used by the caller?

@IRCody yes, a label on the namespace which is to be shared. Allowing the namespace to determine what its content sharing policy is.

which would contain info telling it what other namespace(s) have shared content with the namespace used by the caller

I don't think it is necessary to explicitly name other namespaces. Since namespaces are a top level construct, it is preferable to not have them explicitly reference each other. In the same way, it is preferable to keep client-defined values which are stored in the metadata store out of the configuration file when possible.

Would it be ok to use shareable instead of sharable ? I think both are valid US english, but shareable is more common outside of the USA

From a consistency perspective; I see some other labels use the convention containerd.io/<category>.<property>; should this be containerd.io/namespace.shareable ?

I went ahead and changed all instances of sharable to shareable. Merriam-webster redirects sharable to shareable and that's good enough for me.

I also grepped around and saw what you're saying around that convention. I went ahead and changed this to match so the label is containerd.io/namespace.shareable.

This will give the impression that adding the label, and setting it to "false" would be the reverse; should we check on true / false values?

I think that makes sense. I will add a check that the value is also set to "true". If it's set to anything else will result in the namespace not being sharable. Will also add a sentence stating this in docs/ops.md

If this label is to be a public interface, it should be exported somewhere

not sure what the best location would be for it. I see we have one defined in labels/labels.go, but perhaps there's other / better locations

const LabelUncompressed = "containerd.io/uncompressed"

I'm going to go ahead and move it here, and slightly change the name to be consistent with this format. It seems like the right place for it.

we could restart but I think you need to rebase to pick up the change..

Adds shared content labels to namespaces allowing content to be shared
between namespaces if that namespace is specifically tagged as being
sharable by adding the `containerd.io/namespace/sharable` label to the
namespace.

We can move this along, but I still think this feature needs more work...

  • I think enabling this should likely have an explicit policy
  • Update of content should "copy up", not alter the shared version
  • List operation should handle include the shared content, otherwise there is potential to confuse clients which use both list and stat operations to get a view of available content/images
  • Snapshots, if we dare, maybe committed only

The tar bundles released as `cri-containerd-*.tar.gz` contain a build of runc
linked with a newer version of libseccomp. This dynamically-linked build of runc
was built on Ubuntu 18.04 and will not work on some other distributions, such as
RHEL 7 and Debian 10. Users of such distributions may get a statically-linked
runc binary from https://github.com/opencontainers/runc/releases or build runc
for their own environment.

> **_Deprecation_** These tar bundles are now deprecated and will be removed or
> replaced in containerd 2.0. Projects relying on these tar bundles should use
> the `containerd-*.tar.gz` bundles or work with the containerd community on a
> suitable replacement in containerd 2.0.

See the changelog for complete list of changes
