## v1.41 API changes
[Docker Engine API v1.41 ](https://docs.docker.com/engine/api/v1.41/ ) documentation
API: add "prune" events
This patch adds a new "prune" event type to indicate that pruning of a resource
type completed.
This event-type can be used on systems that want to perform actions after
resources have been cleaned up. For example, Docker Desktop performs an fstrim
after resources are deleted (https://github.com/linuxkit/linuxkit/tree/v0.7/pkg/trim-after-delete).
While the current (remove, destroy) events can provide information on _most_
resources, there is currently no event triggered after the BuildKit build-cache
is cleaned.
Prune events have a `reclaimed` attribute, indicating the amount of space that
was reclaimed (in bytes). The attribute can be used, for example, to use as a
threshold for performing fstrim actions. Reclaimed space for `network` events
will always be 0, but the field is added to be consistent with prune events for
other resources.
To test this patch:
Create some resources:
for i in foo bar baz; do \
docker network create network_$i \
&& docker volume create volume_$i \
&& docker run -d --name container_$i -v volume_$i:/volume busybox sh -c 'truncate -s 5M somefile; truncate -s 5M /volume/file' \
&& docker tag busybox:latest image_$i; \
done;
docker pull alpine
docker pull nginx:alpine
echo -e "FROM busybox\nRUN truncate -s 50M bigfile" | DOCKER_BUILDKIT=1 docker build -
Start listening for "prune" events in another shell:
docker events --filter event=prune
Prune containers, networks, volumes, and build-cache:
docker system prune -af --volumes
See the events that are returned:
docker events --filter event=prune
2020-07-25T12:12:09.268491000Z container prune (reclaimed=15728640)
2020-07-25T12:12:09.447890400Z network prune (reclaimed=0)

## v1.40 API changes
[Docker Engine API v1.40 ](https://docs.docker.com/engine/api/v1.40/ ) documentation
Add HEAD support for /_ping endpoint
Monitoring systems and load balancers are usually configured to use HEAD
requests for health monitoring. The /_ping endpoint currently does not
support this type of request, which means that those systems have fallback
to GET requests.
This patch adds support for HEAD requests on the /_ping endpoint.
Although optional, this patch also returns `Content-Type` and `Content-Length`
headers in case of a HEAD request; Refering to RFC 7231, section 4.3.2:
The HEAD method is identical to GET except that the server MUST NOT
send a message body in the response (i.e., the response terminates at
the end of the header section). The server SHOULD send the same
header fields in response to a HEAD request as it would have sent if
the request had been a GET, except that the payload header fields
(Section 3.3) MAY be omitted. This method can be used for obtaining
metadata about the selected representation without transferring the
representation data and is often used for testing hypertext links for
validity, accessibility, and recent modification.
A payload within a HEAD request message has no defined semantics;
sending a payload body on a HEAD request might cause some existing
implementations to reject the request.
The response to a HEAD request is cacheable; a cache MAY use it to
satisfy subsequent HEAD requests unless otherwise indicated by the
Cache-Control header field (Section 5.2 of [RFC7234]). A HEAD
response might also have an effect on previously cached responses to
GET; see Section 4.3.5 of [RFC7234].
With this patch applied, either `GET` or `HEAD` requests work; the only
difference is that the body is empty in case of a `HEAD` request;
curl -i --unix-socket /var/run/docker.sock http://localhost/_ping

The client is also updated to use `HEAD` by default, but fallback to `GET`
if the daemon does not support this method.

2019-01-14 12:08:49 -05:00
* The `/_ping` endpoint can now be accessed both using `GET` or `HEAD` requests.
when accessed using a `HEAD` request, all headers are returned, but the body
is empty (`Content-Length: 0`). This change is not versioned, and affects all
API versions if the daemon has this patch. Clients are recommended to try
using `HEAD` , but fallback to `GET` if the `HEAD` requests fails.
* `GET /_ping` and `HEAD /_ping` now set `Cache-Control` and `Pragma` headers to
prevent the result from being cached. This change is not versioned, and affects
all API versions if the daemon has this patch.

`1` ), the endpoint returns all networks that are not in use by a container. When
set to `false` (or `0` ), only networks that are in use by one or more containers
are returned.
2018-10-26 09:51:23 -04:00
* `GET /nodes` now supports a filter type `node.label` filter to filter nodes based
on the node.label. The format of the label filter is `node.label=<key>` /`node.label=< key > =< value > `
to return those with the specified labels, or `node.label!=<key>` /`node.label!=< key > =< value > `
to return those without the specified labels.
2019-04-16 06:27:32 -04:00
* `POST /containers/create` now accepts a `fluentd-async` option in `HostConfig.LogConfig.Config`
when using the Fluentd logging driver. This option deprecates the `fluentd-async-connect`
option, which remains funtional, but will be removed in a future release. Users
are encouraged to use the `fluentd-async` option going forward. This change is
not versioned, and affects all API versions if the daemon has this patch.
2019-04-16 06:42:54 -04:00
* `POST /containers/create` now accepts a `fluentd-request-ack` option in
`HostConfig.LogConfig.Config` when using the Fluentd logging driver. If enabled,
the Fluentd logging driver sends the chunk option with a unique ID. The server
will respond with an acknowledgement. This option improves the reliability of
the message transmission. This change is not versioned, and affects all API
versions if the daemon has this patch.

daemon: use 'private' ipc mode by default
This changes the default ipc mode of daemon/engine to be private,
meaning the containers will not have their /dev/shm bind-mounted
from the host by default. The benefits of doing this are:
1. No leaked mounts. Eliminate a possibility to leak mounts into
other namespaces (and therefore unfortunate errors like "Unable to
remove filesystem for <ID>: remove /var/lib/docker/containers/<ID>/shm:
device or resource busy").
2. Working checkpoint/restore. Make `docker checkpoint`
not lose the contents of `/dev/shm`, but save it to
the dump, and be restored back upon `docker start --checkpoint`
(currently it is lost -- while CRIU handles tmpfs mounts,
the "shareable" mount is seen as external to container,
and thus rightfully ignored).
3. Better security. Currently any container is opened to share
its /dev/shm with any other container.
Obviously, this change will break the following usage scenario:
$ docker run -d --name donor busybox top
$ docker run --rm -it --ipc container:donor busybox sh
Error response from daemon: linux spec namespaces: can't join IPC
of container <ID>: non-shareable IPC (hint: use IpcMode:shareable
for the donor container)
The soution, as hinted by the (amended) error message, is to
explicitly enable donor sharing by using --ipc shareable:
$ docker run -d --name donor --ipc shareable busybox top
Compatibility notes:
1. This only applies to containers created _after_ this change.
Existing containers are not affected and will work fine
as their ipc mode is stored in HostConfig.
2. Old backward compatible behavior ("shareable" containers
by default) can be enabled by either using
`--default-ipc-mode shareable` daemon command line option,
or by adding a `"default-ipc-mode": "shareable"`
line in `/etc/docker/daemon.json` configuration file.
3. If an older client (API < 1.40) is used, a "shareable" container
is created. A test to check that is added.

ContainerWait on remove: don't stuck on rm fail
Currently, if a container removal has failed for some reason,
any client waiting for removal (e.g. `docker run --rm`) is
stuck, waiting for removal to succeed while it has failed already.
For more details and the reproducer, please check
https://github.com/moby/moby/issues/34945
This commit addresses that by allowing `ContainerWait()` with
`container.WaitCondition == "removed"` argument to return an
error in case of removal failure. The `ContainerWaitOKBody`
stucture returned to a client is amended with a pointer to `struct Error`,
containing an error message string, and the `Client.ContainerWait()`
is modified to return the error, if any, to the client.
Note that this feature is only available for API version >= 1.34.
In order for the old clients to be unstuck, we just close the connection

* `POST /containers/(name)/wait?condition=removed` now also also returns
in case of container removal failure. A pointer to a structure named
`Error` added to the response JSON in order to indicate a failure.
If `Error` is `null` , container removal has succeeded, otherwise
the test of an error message indicating why container removal has failed
is available from `Error.Message` field.

## v1.33 API changes

* `GET /events` now supports filtering 4 more kinds of events: `config` , `node` ,
ContainerWait on remove: don't stuck on rm fail
Currently, if a container removal has failed for some reason,
any client waiting for removal (e.g. `docker run --rm`) is
stuck, waiting for removal to succeed while it has failed already.
For more details and the reproducer, please check
https://github.com/moby/moby/issues/34945
This commit addresses that by allowing `ContainerWait()` with
`container.WaitCondition == "removed"` argument to return an
error in case of removal failure. The `ContainerWaitOKBody`
stucture returned to a client is amended with a pointer to `struct Error`,
containing an error message string, and the `Client.ContainerWait()`
is modified to return the error, if any, to the client.
Note that this feature is only available for API version >= 1.34.
In order for the old clients to be unstuck, we just close the connection
without writing anything -- this causes client's error.
Now, docker-cli would need a separate commit to bump the API to 1.34

## v1.32 API changes
[Docker Engine API v1.32 ](https://docs.docker.com/engine/api/v1.32/ ) documentation
Implement none, private, and shareable ipc modes
Since the commit d88fe447df0e8 ("Add support for sharing /dev/shm/ and
/dev/mqueue between containers") container's /dev/shm is mounted on the
host first, then bind-mounted inside the container. This is done that
way in order to be able to share this container's IPC namespace
(and the /dev/shm mount point) with another container.
Unfortunately, this functionality breaks container checkpoint/restore
(even if IPC is not shared). Since /dev/shm is an external mount, its
contents is not saved by `criu checkpoint`, and so upon restore any
application that tries to access data under /dev/shm is severily
disappointed (which usually results in a fatal crash).
This commit solves the issue by introducing new IPC modes for containers
(in addition to 'host' and 'container:ID'). The new modes are:
- 'shareable': enables sharing this container's IPC with others
(this used to be the implicit default);
- 'private': disables sharing this container's IPC.
In 'private' mode, container's /dev/shm is truly mounted inside the
container, without any bind-mounting from the host, which solves the
issue.
While at it, let's also implement 'none' mode. The motivation, as
eloquently put by Justin Cormack, is:
> I wondered a while back about having a none shm mode, as currently it is
> not possible to have a totally unwriteable container as there is always
> a /dev/shm writeable mount. It is a bit of a niche case (and clearly
> should never be allowed to be daemon default) but it would be trivial to
> add now so maybe we should...
...so here's yet yet another mode:
- 'none': no /dev/shm mount inside the container (though it still
has its own private IPC namespace).
Now, to ultimately solve the abovementioned checkpoint/restore issue, we'd
need to make 'private' the default mode, but unfortunately it breaks the
backward compatibility. So, let's make the default container IPC mode
per-daemon configurable (with the built-in default set to 'shareable'
for now). The default can be changed either via a daemon CLI option
(--default-shm-mode) or a daemon.json configuration file parameter
of the same name.
Note one can only set either 'shareable' or 'private' IPC modes as a
daemon default (i.e. in this context 'host', 'container', or 'none'
do not make much sense).
Some other changes this patch introduces are:
1. A mount for /dev/shm is added to default OCI Linux spec.
2. IpcMode.Valid() is simplified to remove duplicated code that parsed
'container:ID' form. Note the old version used to check that ID does
not contain a semicolon -- this is no longer the case (tests are
modified accordingly). The motivation is we should either do a
proper check for container ID validity, or don't check it at all
(since it is checked in other places anyway). I chose the latter.
3. IpcMode.Container() is modified to not return container ID if the
mode value does not start with "container:", unifying the check to
be the same as in IpcMode.IsContainer().
3. IPC mode unit tests (runconfig/hostconfig_test.go) are modified
to add checks for newly added values.

* `POST /containers/create` now accepts additional values for the
`HostConfig.IpcMode` property. New values are `private` , `shareable` ,
and `none` .
2017-08-14 16:23:57 -04:00
* `DELETE /networks/{id or name}` fixed issue where a `name` equal to another
network's name was able to mask that `id` . If both a network with the given
_name_ exists, and a network with the given _id_ , the network with the given
_id_ is now deleted. This change is not versioned, and affects all API versions
if the daemon has this patch.

Add containers’ networks to /containers/json
After addition of multi-host networking in Docker 1.9, Docker Remote
API is still returning only the network specified during creation
of the container in the “List Containers” (`/containers/json`) endpoint:
...
"HostConfig": {
"NetworkMode": "default"
},
The list of networks containers are attached to is only available at
Get Container (`/containers/<id>/json`) endpoint.
This does not allow applications utilizing multi-host networking to
be built on top of Docker Remote API.
Therefore I added a simple `"NetworkSettings"` section to the
`/containers/json` endpoint. This is not identical to the NetworkSettings
returned in Get Container (`/containers/<id>/json`) endpoint. It only
contains a single field `"Networks"`, which is essentially the same
value shown in inspect output of a container.
This change adds the following section to the `/containers/json`:
"NetworkSettings": {
"Networks": {
"bridge": {
"EndpointID": "2cdc4edb1ded3631c81f57966563e...",
"Gateway": "172.17.0.1",
"IPAddress": "172.17.0.2",
"IPPrefixLen": 16,
"IPv6Gateway": "",
"GlobalIPv6Address": "",
"GlobalIPv6PrefixLen": 0,
"MacAddress": "02:42:ac:11:00:02"
}
}
}
This is of type `SummaryNetworkSettings` type, a minimal version of
`api/types#NetworkSettings`.
Actually all I need is the network name and the IPAddress fields. If folks
find this addition too big, I can create a `SummaryEndpointSettings` field
as well, containing just the IPAddress field.
