Add support for ALL_PROXY
Support for ALL_PROXY as default build-arg was added recently in
buildkit and the classic builder.

This patch adds the `ALL_PROXY` environment variable to the list of
configurable proxy variables, and updates the documentation.

Use designated test domains (RFC2606) in tests
Some tests were using domain names that were intended to be "fake", but are
actually registered domain names (such as mycorp.com).

Even though we were not actually making connections to these domains, it's
better to use domains that are designated for testing/examples in RFC2606:

ForwardAllSignals: check if channel is closed, and remove warning
Commit fff164c22e modified ForwardAllSignals to
take `SIGURG` signals into account, which can be generated by the Go runtime
on Go 1.14 and up as an interrupt to support pre-emptable system calls on Linux.

With the updated code, the signal (`s`) would sometimes be `nil`, causing spurious
(but otherwise harmless) warnings to be printed;

    Unsupported signal: <nil>. Discarding.

To debug this issue, I patched v20.10.4 to handle `nil`, and added a debug line
to print the signal in all cases;

```patch

This patch checks if the channel is closed, and removes the warning (to prevent warnings if new
signals are added that are not in our known list of signals)

We should also consider updating `notfiyAllSignals()`, which currently forwards
_all_ signals (`signal.Notify(sigc)` without passing a list of signals), and
instead pass it "all signals _minus_ the signals we don't want forwarded":

Brian Goff fff164c22e Ignore SIGURG on Linux.
In go1.14+, SIGURG is used by the runtime to handle preemtable system
calls.
In practice this signal caught *frequently*.

Merge pull request #2678 from thaJeztah/fix_rm_force_exit_status
Return zero exit-code when force-removing non-existing containers
2020-08-27 14:40:08 -07:00
Sebastiaan van Stijn 9a071a993a
Return zero exit-code when force-removing non-existing containers
When using `docker rm` / `docker container rm` with the `-f` / `--force` option, attempts to remove non-existing containers should print a warning, but should return a zero exit code ("successful").

Currently, a non-zero exit code is returned, marking the removal as "failed";

	$ docker rm -fv 798c9471b695
	Error: No such container: 798c9471b695
	$ echo $?
	1

The command should match the behavior of `rm` / `rm -f`, with the exception that
a warning is printed (instead of silently ignored):

Running `rm` with `-f` silences output and returns a zero exit code:

    touch some-file && rm -f no-such-file some-file; echo exit code: $?; ls -la
    # exit code: 0
    # total 0
    # drwxr-xr-x    2 sebastiaan  staff    64 Aug 14 12:17 .
    # drwxr-xr-x  199 sebastiaan  staff  6368 Aug 14 12:13 ..

    mkdir some-directory && rm -rf no-such-directory some-directory; echo exit code: $?; ls -la
    # exit code: 0
    # total 0
    # drwxr-xr-x    2 sebastiaan  staff    64 Aug 14 12:17 .
    # drwxr-xr-x  199 sebastiaan  staff  6368 Aug 14 12:13 ..

Note that other reasons for a delete to fail should still result in a non-zero
exit code, matching the behavior of `rm`. For instance, in the example below,
the `rm` failed because directories can only be removed if the `-r` option is used;

    touch some-file && mkdir some-directory && rm -f some-directory no-such-file some-file; echo exit code: $?; ls -la
    # rm: some-directory: is a directory
    # exit code: 1
    # total 0
    # drwxr-xr-x    3 sebastiaan  staff    96 Aug 14 14:15 .
    # drwxr-xr-x  199 sebastiaan  staff  6368 Aug 14 12:13 ..
    # drwxr-xr-x    2 sebastiaan  staff    64 Aug 14 14:15 some-directory

This patch updates the `docker rm` / `docker container rm` command to not produce
an error when attempting to remove a missing containers, and instead only print
the error, but return a zero (0) exit code.

With this patch applied:

    docker create --name mycontainer busybox \
    && docker rm nosuchcontainer mycontainer; \
    echo exit code: $?; \
    docker ps -a --filter name=mycontainer

Brian Goff ccd9d633bb Set platform on container create API.
Previously we only set the platform when performing a pull, which is
only initiated if pull always is set, or if the image reference does not
exist in the daemon.

The daemon now supports specifying which platform you wanted on
container create so it can validate the image reference is the platform
you thought you were getting.

Nick Adcock 154a1f6df8 Reverse order of long-form ports
Reverses the order long-form port options when converted to short-form
to correctly match the documentation and `docker service create`.

Post change `-p published=8111,target=8112` is the equivalent of
`8111:8112`

Fix docker ps --format with templating functions
Before this patch, using a template that used templating functions (such as
`lower` or `json`) caused the command to fail in the pre-processor step (in
`buildContainerListOptions`):

    docker ps --format='{{upper .Names}}'
    template: :1:8: executing "" at <.Names>: invalid value; expected string

This problem was due to the pre-processing using a different "context" type than
was used in the actual template, and custom functions to not be defined when
instantiating the Go template.

With this patch, using functions in templates works correctly:

    docker ps --format='{{upper .Names}}'
    MUSING_NEUMANN
    ELOQUENT_MEITNER

Do not disable sig-proxy when using a TTY
This partially reverts e0b59ab52b,
and does not automatically disable proxying signals in TTY-mode

Before this change:
------------------------------------

Start a container with a TTY in one shell:

```
docker run -it --init --name repro-28872 busybox sleep 30
```

then, in another shell, kill the docker cli:

```
kill `pgrep -f repro-28872`
```

Notice that the CLI was killed, but the signal not forwarded to the container;
the container continues running

```
docker container inspect --format '{{ .State.Status }}' repro-28872
running

docker container rm -f repro-28872
```

After this change:
------------------------------------

Start a container with a TTY in one shell:

```
docker run -it --init --name repro-28872 busybox sleep 30
```

then, in another shell, kill the docker cli:

```
kill `pgrep -f repro-28872`
```

Verify that the signal was forwarded to the container, and the container exited

```
docker container inspect --format '{{ .State.Status }}' repro-28872
exited

docker container rm -f repro-28872
```
