Allow Dockerfile from outside build-context Historically, the Dockerfile had to be insde the build-context, because it was sent as part of the build-context. https://github.com/moby/moby/pull/31236/commits/3f6dc81e10b8b813fffaa9b4167a60c5a507fa38 added support for passing the Dockerfile through stdin, in which case the contents of the Dockerfile is injected into the build-context. This patch uses the same mechanism for situations where the location of the Dockerfile is passed, and its path is outside of the build-context. Before this change: $ mkdir -p myproject/context myproject/dockerfiles && cd myproject $ echo "hello" > context/hello $ echo -e "FROM busybox\nCOPY /hello /\nRUN cat /hello" > dockerfiles/Dockerfile $ docker build --no-cache -f $PWD/dockerfiles/Dockerfile $PWD/context unable to prepare context: the Dockerfile (/Users/sebastiaan/projects/test/dockerfile-outside/myproject/dockerfiles/Dockerfile) must be within the build context After this change: $ mkdir -p myproject/context myproject/dockerfiles && cd myproject $ echo "hello" > context/hello $ echo -e "FROM busybox\nCOPY /hello /\nRUN cat /hello" > dockerfiles/Dockerfile $ docker build --no-cache -f $PWD/dockerfiles/Dockerfile $PWD/context Sending build context to Docker daemon 2.607kB Step 1/3 : FROM busybox ---> 6ad733544a63 Step 2/3 : COPY /hello / ---> 9a5ae1c7be9e Step 3/3 : RUN cat /hello ---> Running in 20dfef2d180f hello Removing intermediate container 20dfef2d180f ---> ce1748f91bb2 Successfully built ce1748f91bb2 Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

Fix labels copying value from environment variables This patch fixes a bug where labels use the same behavior as `--env`, resulting in a value to be copied from environment variables with the same name as the label if no value is set (i.e. a simple key, no `=` sign, no value). An earlier pull request addressed similar cases for `docker run`; 2b17f4c8a8caad552025edb05a73db683fb8a5c6, but this did not address the same situation for (e.g.) `docker service create`. Digging in history for this bug, I found that use of the `ValidateEnv` function for labels was added in the original implementation of the labels feature in https://github.com/docker/docker/commit/abb5e9a0777469e64fe2c7ecfa66ea01083d2071#diff-ae476143d40e21ac0918630f7365ed3cR34 However, the design never intended it to expand environment variables, and use of this function was either due to either a "copy/paste" of the equivalent `--env` flags, or a misunderstanding (the name `ValidateEnv` does not communicate that it also expands environment variables), and the existing `ValidateLabel` was designed for _engine_ labels (which required a value to be set). Following the initial implementation, other parts of the code followed the same (incorrect) approach, therefore leading the bug to be introduced in services as well. This patch: - updates the `ValidateLabel` to match the expected validation rules (this function is no longer used since 31dc5c0a9a8bdc11c7ad335aebb753ed527caa5a), and the daemon has its own implementation) - corrects various locations in the code where `ValidateEnv` was used instead of `ValidateLabel`. Before this patch: ```bash export SOME_ENV_VAR=I_AM_SOME_ENV_VAR docker service create --label SOME_ENV_VAR --tty --name test busybox docker service inspect --format '{{json .Spec.Labels}}' test {"SOME_ENV_VAR":"I_AM_SOME_ENV_VAR"} ``` After this patch: ```bash export SOME_ENV_VAR=I_AM_SOME_ENV_VAR docker service create --label SOME_ENV_VAR --tty --name test busybox docker container inspect --format '{{json .Config.Labels}}' test {"SOME_ENV_VAR":""} ``` Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

Add version annotation to various flags added in 1.13 Pull request https://github.com/docker/docker/pull/27745 added support for the client to talk to older versions of the daemon. Various flags were added to docker 1.13 that are not compatible with older daemons. This PR adds annotations to those flags, so that they are automatically hidden if the daemon is older than docker 1.13 (API 1.25). Not all new flags affect the API (some are client-side only). The following PR's added new flags to docker 1.13 that affect the API; - https://github.com/docker/docker/pull/23430 added `--cpu-rt-period`and `--cpu-rt-runtime` - https://github.com/docker/docker/pull/27800 / https://github.com/docker/docker/pull/25317 added `--group` / `--group-add` / `--group-rm` - https://github.com/docker/docker/pull/27702 added `--network` to `docker build` - https://github.com/docker/docker/pull/25962 added `--attachable` to `docker network create` - https://github.com/docker/docker/pull/27998 added `--compose-file` to `docker stack deploy` - https://github.com/docker/docker/pull/22566 added `--stop-timeout` to `docker run` and `docker create` - https://github.com/docker/docker/pull/26061 added `--init` to `docker run` and `docker create` - https://github.com/docker/docker/pull/26941 added `--init-path` to `docker run` and `docker create` - https://github.com/docker/docker/pull/27958 added `--cpus` on `docker run` / `docker create` - https://github.com/docker/docker/pull/27567 added `--dns`, `--dns-opt`, and `--dns-search` to `docker service create` - https://github.com/docker/docker/pull/27596 added `--force` to `docker service update` - https://github.com/docker/docker/pull/27857 added `--hostname` to `docker service create` - https://github.com/docker/docker/pull/28031 added `--hosts`, `--host-add` / `--host-rm` to `docker service create` and `docker service update` - https://github.com/docker/docker/pull/28076 added `--tty` on `docker service create` / `docker service update` - https://github.com/docker/docker/pull/26421 added `--update-max-failure-ratio`, `--update-monitor` and `--rollback` on `docker service update` - https://github.com/docker/docker/pull/27369 added `--health-cmd`, `--health-interval`, `--health-retries`, `--health-timeout` and `--no-healthcheck` options to `docker service create` and `docker service update` Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
