Working directory processing was handled differently for Hyper-V and Windows-Server containers, as annotated in the builder documentation (updated in this PR). For Hyper-V containers, the working directory set by WORKDIR was not created. This PR makes Hyper-V containers work the same as Windows Server containers (and the same as Linux).
Example (only applies to Hyper-V containers, so not reproducible under CI environment)
Dockerfile:
FROM microsoft/nanoserver
WORKDIR c:\installer
ENV GOROOT=c:\installer
ADD go.exe .
RUN go --help
Running on Windows Server 2016, using docker master without this change, but with daemon set to --exec-opt isolation=hyperv as it would be for Client operating systems.

Now compare the same results after this PR. Again, first with no explicit isolation (defaulting to Hyper-V containers as that's what the daemon it set to) - note it now succeeds 😄

doc show documentation for package or symbol
env print Go environment information
fix run go tool fix on packages
fmt run gofmt on package sources
generate generate Go files by processing source
get download and install packages and dependencies
install compile and install packages and dependencies
list list packages
run compile and run Go program
test test packages
tool run specified go tool
version print Go version
vet run go tool vet on packages
Use "go help [command]" for more information about a command.
Additional help topics:

The command 'cmd /S /C go --help' returned a non-zero code: 2
And the same with forcing process isolation. Also works 😄

PS E:\docker\build\unifyworkdir>
This allows the user to set a logging mode to "blocking" (default), or
"non-blocking", which uses the ring buffer as a proxy to the real log
driver.
This allows a container to never be blocked on stdio at the cost of
dropping log messages.
Introduces 2 new log-opts that works for all drivers, `log-mode` and
`log-size`. `log-mode` takes a value of "blocking", or "non-blocking"
I chose not to implement this as a bool since it is difficult to
determine if the mode was set to false vs just not set... especially
difficult when merging the default daemon config with the container config.
`log-size` takes a size string, e.g. `2MB`, which sets the max size
of the ring buffer. When the max size is reached, it will start
dropping log messages.

This fix tries to improve the display of `docker service ls`
and adds `--format` flag to `docker service ls`.
In addition to `--format` flag, several other improvement:
1. Updates `docker stacks service`.
2. Adds `servicesFormat` to config file.

This fix tries to address the issue raised in 28176 where
text frame was used in websocket attach endpoint. In case
the data send out contains non utf8 data, the connection
will be closed in certain browsers, e.g., Safari.
This fix address the issue by change `PayloadType` to `BinaryFrame`.
This fix is tested manually with Safari. The docker daemon is inside a Linux Virtual Machine.
Create a container with:
```
docker run -itd --name websocket busybox sh -c "while true; do echo -e 'he\\xc3\\x28o'; sleep 5; done"
```
Use the following url (172.16.66.128:2375 is the tcp address of the daemon):
```
file:///websocket.html?url=ws://172.16.66.128:2375/v1.25/containers/websocket/attach/ws?logs=1&stderr=1&stdout=1&stream=1&stdin=1
```
and the following html:
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Websocket</title>
<script type="text/javascript">
function DockerWebSocket() {
if ("WebSocket" in window) {
console.log("WebSocket is supported by Browser...")
// Remove '?url=' prefix
url = window.location.search.replace(/^(\?url=)/,"");
console.log("URL ["+url+"]...");
var ws = new WebSocket(url);
ws.onopen = function() {
console.log("Connection is opened...");
};
ws.onclose = function() {
console.log("Connection is closed...");
};
ws.onmessage = function (e) {
if (typeof e.data === "string") {
alert("WebSocket received text message ["+e.data+"]!")
} else {
console.log("Message is received...")
var blobReader = new FileReader();
blobReader.onload = function(event) {
console.log(JSON.stringify(blobReader.result))
};
blobReader.readAsText(e.data)
console.log("Message complete...")
}
};
} else {
alert("WebSocket is not supported by Browser!");
}
}
</script>

This fix tries to address the issue raised in 29972 where
it was not possible to specify `--read-only` for `docker service create`
and `docker service update`, in order to have the container's root file
system to be read only.
This fix adds `--read-only` and update the `ReadonlyRootfs` in `HostConfig`
through `service create` and `service update`.

Integration test has been added.

This fix tries to address the enhancement proposal raised in
27178 for filtering based on published or exposed ports of
`docker ps --filter`.
In this fix, two filter options, `publish` and `expose` have
been added to take either `<port>[/<protocol>]` or `<from>-<to>[/<protocol>]`
and filtering on containers.
An integration test has been added to cover the changes.
This fix fixes 27178.

This fix made several updates:
1. Update opts.MemBytes so that default value will not show up.
The reason is that in case a default value is decided by daemon,
instead of client, we actually want to not show default value.
2. Move `docker run/create/build` to use opts.MemBytes for `--shm-size`
This is to bring consistency between daemon and docker run
3. docs updates.
