fix: modify streaming io url and add docs of sandboxer and io_type #10190

abel-von · 2024-05-08T07:23:20Z

sandbox address should be in the form of
<ttrpc|grpc>+<unix|vsock|hvsock>://<uds-path|vsock-cid:vsock-port|uds-path:hvsock-port>
for example: ttrpc+hvsock:///run/test.hvsock:1024
or: grpc+vsock://1111111:1024
and the Stdin/Stdout/Stderr will add a streaming_id as a parameter of the url result form is:
<ttrpc|grpc>+<unix|vsock|hvsock>://<uds-path|vsock-cid:vsock-port|uds-path:hvsock-port>?streaming_id= for example ttrpc+hvsock:///run/test.hvsock:1024?streaming_id=111111 or grpc+vsock://1111111:1024?streaming_id=222222

Change the current logic of add a streaming in the path, because unix domain socket or hybrid vsock alread have the path field and add a streaming suffix makes the logic complecated.

Hi @abel-von. 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.

Details

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

 // NewStreamExecIO creates exec io with streaming.
+// address should be in the form of
+// <ttrpc|grpc>+<unix|vsock|hvsock>://<uds-path|vsock-cid:vsock-port|uds-path:hvsock-port>


I think we don't need to list all the combinations in here. Suggest to use protocol://address?streaming_id=xyz.

pull-containerd-k8s-e2e-ec2 seems failed for all new PRs, It seems that some error from execution environment make this error. @fuweid

Left two comments and one question:

When containerd restarts, the streaming_id is the same. Is it possible to establish stream tunnel successfully with same ID? If not, we need to consider to how to recover this and please file issue to track this. Thanks

 // WithStreams creates new streams for the container io.
+// address should be in the form of protocol://address


Suggested change

// address should be in the form of protocol://address

// The stream address is in format of `protocol://address`.

// It allocates ContainerID-stdin, ContainerID-stdout and ContainerID-stderr as streaming IDs.

// For example, that advertiser address of shim is `ttrpc+unix:///run/demo.sock` and container ID is `app`.

// There are three streaming IDs if stdin is enable and TTY is disable.

//

// * Stdin: app-stdin

// * Stdout: app-stdout

// * stderr: app-stderr

//

// These streaming IDs will be used as unique key to establish stream tunnel.

I think streaming server should support reconnection of the same ID, and add this in the comment, please check. @fuweid

abel-von · 2024-05-13T09:50:20Z

and add a fix of restart recovey of container io in restart.go https://github.com/containerd/containerd/pull/10190/files#diff-ad49a10c586e0f81890f9ee72f6dcc26ce03607c37b4c4856786f459e1e43a38 please take a look.
