Fix cpu/memory limits and reservations being reset on service update
Before this change:
----------------------------------------------------

Create a service with reservations and limits for memory and cpu:

    docker service create --name test \
      --limit-memory=100M --limit-cpu=1 \
      --reserve-memory=100M --reserve-cpu=1 \
      nginx:alpine

Verify the configuration

    docker service inspect --format '{{json .Spec.TaskTemplate.Resources}}' test
    {
      "Limits": {
        "NanoCPUs": 1000000000,
        "MemoryBytes": 104857600
      },
      "Reservations": {
        "NanoCPUs": 1000000000,
        "MemoryBytes": 104857600
      }
    }

Update just CPU limit and reservation:

    docker service update --limit-cpu=2 --reserve-cpu=2 test

Notice that the memory limit and reservation is not preserved:

    docker service inspect --format '{{json .Spec.TaskTemplate.Resources}}' test
    {
      "Limits": {
        "NanoCPUs": 2000000000
      },
      "Reservations": {
        "NanoCPUs": 2000000000
      }
    }

Update just Memory limit and reservation:

    docker service update --limit-memory=200M --reserve-memory=200M test

Notice that the CPU limit and reservation is not preserved:

    docker service inspect --format '{{json .Spec.TaskTemplate.Resources}}' test
    {
      "Limits": {
        "MemoryBytes": 209715200
      },
      "Reservations": {
        "MemoryBytes": 209715200
      }
    }

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

      nginx:alpine

Verify the configuration

    docker service inspect --format '{{json .Spec.TaskTemplate.Resources}}' test
    {
      "Limits": {
        "NanoCPUs": 1000000000,

        "NanoCPUs": 1000000000,
        "MemoryBytes": 104857600
      }
    }

Update just CPU limit and reservation:

    docker service update --limit-cpu=2 --reserve-cpu=2 test

Confirm that the CPU limits/reservations are updated, but memory limit and reservation are preserved:

    docker service inspect --format '{{json .Spec.TaskTemplate.Resources}}' test
    {
      "Limits": {
        "NanoCPUs": 2000000000,

      },
      "Reservations": {
        "NanoCPUs": 2000000000,
        "MemoryBytes": 104857600
      }
    }

Update just Memory limit and reservation:

    docker service update --limit-memory=200M --reserve-memory=200M test

Confirm that the Mempry limits/reservations are updated, but CPU limit and reservation are preserved:

    docker service inspect --format '{{json .Spec.TaskTemplate.Resources}}' test
    {
      "Limits": {
        "NanoCPUs": 2000000000,

      },
      "Reservations": {
        "NanoCPUs": 2000000000,
        "MemoryBytes": 209715200
      }

Kir Kolyshkin 6f8070deb2 Switch from x/net/context to context
Since go 1.7, "context" is a standard package. Since go 1.9,
x/net/context merely provides some types aliased to those in
the standard context package.

The changes were performed by the following script:

for f in $(git ls-files \*.go | grep -v ^vendor/); do
	sed -i 's|golang.org/x/net/context|context|' $f
	goimports -w $f
	for i in 1 2; do
		awk '/^$/ {e=1; next;}
			/\t"context"$/ {e=0;}
			{if (e) {print ""; e=0}; print;}' < $f > $f.new && \
				mv $f.new $f
		goimports -w $f
	done
done

[v2: do awk/goimports fixup twice]

Fix service update --host-rm not being granular enough
Removing a host by `<host>:<ip>` should only remove occurences of the host with
a matching IP-address, instead of removing all entries for that host.

In addition, combining `--host-rm` and `--host-add` for the same host should
result in the new host being added.

This patch fixes the way the diff is calculated to allow combining
removing/adding, and to support entries having both a canonical, and aliases.
Aliases cannot be added by the CLI, but are supported in the Service spec, thus
should be taken into account:

Entries can be removed by either a specific `<host-name>:<ip-address>`
mapping, or by `<host>` alone:

 - If both IP-address and host-name is provided, only remove the hostname
   from entries that match the given IP-address.
 - If only a host-name is provided, remove the hostname from any entry it
   is part of (either as _canonical_ host-name, or as _alias_).
 - If, after removing the host-name from an entry, no host-names remain in
   the entry, the entry itself should be removed.

For example, the list of host-entries before processing could look like this:

    hosts = &[]string{
        "127.0.0.2 host3 host1 host2 host4",
        "127.0.0.1 host1 host4",
        "127.0.0.3 host1",
        "127.0.0.1 host1",
    }

Removing `host1` removes every occurrence:

    hosts = &[]string{
        "127.0.0.2 host3 host2 host4",
        "127.0.0.1 host4",
    }

Whereas removing `host1:127.0.0.1` only remove the host if the IP-address matches:

    hosts = &[]string{
        "127.0.0.2 host3 host1 host2 host4",
        "127.0.0.1 host4",
        "127.0.0.3 host1",
    }

Before this patch:

    $ docker service create --name my-service --host foo:127.0.0.1  --host foo:127.0.0.2 --host foo:127.0.0.3 nginx:alpine
    $ docker service update --host-rm foo:127.0.0.1 --host-add foo:127.0.0.4 my-service
    $ docker service inspect --format '{{.Spec.TaskTemplate.ContainerSpec.Hosts}}' my-service
    []

After this patch is applied:

    $ docker service create --name my-service --host foo:127.0.0.1  --host foo:127.0.0.2 --host foo:127.0.0.3 nginx:alpine
    $ docker service update --host-rm foo:127.0.0.1 --host-add foo:127.0.0.5 my-service
    $ docker service inspect --format '{{.Spec.TaskTemplate.ContainerSpec.Hosts}}' my-service

Fix --network-add adding duplicate networks
When adding a network using `docker service update --network-add`,
the new network was added by _name_.

Existing entries in a service spec are listed by network ID, which
resulted in the CLI not detecting duplicate entries for the same
network.

This patch changes the behavior to always use the network-ID,
so that duplicate entries are correctly caught.

Before this change;

    $ docker network create -d overlay foo
    $ docker service create --name=test --network=foo nginx:alpine
    $ docker service update --network-add foo test
    $ docker service inspect --format '{{ json .Spec.TaskTemplate.Networks}}' test
    [
      {
        "Target": "9ot0ieagg5xv1gxd85m7y33eq"
      },
      {
        "Target": "9ot0ieagg5xv1gxd85m7y33eq"
      }
    ]

After this change:

    $ docker network create -d overlay foo
    $ docker service create --name=test --network=foo nginx:alpine
    $ docker service update --network-add foo test
    service is already attached to network foo

Merge pull request #651 from thaJeztah/fix-extra-host-sorting
Preserve sort-order of extra hosts, and allow duplicate entries
2017-10-30 20:38:10 +01:00
Sebastiaan van Stijn dbdf8f6468
Preserve sort-order of extra hosts, and allow duplicate entries
Extra hosts (`extra_hosts` in compose-file, or `--hosts` in services) adds
custom host/ip mappings to the container's `/etc/hosts`.

The current implementation used a `map[string]string{}` as intermediate
storage, and sorted the results alphabetically when converting to a service-spec.

As a result, duplicate hosts were removed, and order of host/ip mappings was not
preserved (in case the compose-file used a list instead of a map).

According to the **host.conf(5)** man page (http://man7.org/linux/man-pages/man5/host.conf.5.html)

    multi  Valid values are on and off.  If set to on, the resolver
      library will return all valid addresses for a host that
      appears in the /etc/hosts file, instead of only the first.
      This is off by default, as it may cause a substantial
      performance loss at sites with large hosts files.

Multiple entries for a host are allowed, and even required for some situations,
for example, to add mappings for IPv4 and IPv6 addreses for a host, as illustrated
by the example hosts file in the **hosts(5)** man page (http://man7.org/linux/man-pages/man5/hosts.5.html):

    # The following lines are desirable for IPv4 capable hosts
    127.0.0.1       localhost

    # 127.0.1.1 is often used for the FQDN of the machine
    127.0.1.1       thishost.mydomain.org  thishost
    192.168.1.10    foo.mydomain.org       foo
    192.168.1.13    bar.mydomain.org       bar
    146.82.138.7    master.debian.org      master
    209.237.226.90  www.opensource.org

    # The following lines are desirable for IPv6 capable hosts
    ::1             localhost ip6-localhost ip6-loopback
    ff02::1         ip6-allnodes
    ff02::2         ip6-allrouters

This patch changes the intermediate storage format to use a `[]string`, and only
sorts entries if the input format in the compose file is a mapping. If the input
format is a list, the original sort-order is preserved.

Fix flag description for --host-add
The `--host-add` flag adds a new `host:ip` mapping. Even though
adding an entry is idempotent (adding the same mapping multiple
times does not update the service's definition), it does not
_update_  an existing mapping with a new IP-address (multiple
IP-addresses can be defined for a host).

This patch removes the "or update" part from the flag's
description.

Use non-detached mode as default for service commands
Commit 330a0035334871d92207b583c1c36d52a244753f added a `--detach=false` option
to various service-related commands, with the intent to make this the default in
a future version (17.09).

This patch changes the default to use "interactive" (non-detached), allowing
users to override this by setting the `--detach` option.

To prevent problems when connecting to older daemon versions (17.05 and below,
see commit db60f25561), the detach option is
ignored for those versions, and detach is always true.

Before this change, a warning was printed to announce the upcoming default:

    $ docker service create nginx:alpine
    saxiyn3pe559d753730zr0xer
    Since --detach=false was not specified, tasks will be created in the background.
    In a future release, --detach=false will become the default.

After this change, no warning is printed, but `--detach` is disabled;

    $ docker service create nginx:alpine
    y9jujwzozi0hwgj5yaadzliq6
    overall progress: 1 out of 1 tasks
    1/1: running   [==================================================>]
    verify: Service converged

Setting the `--detach` flag makes the cli use the pre-17.06 behavior:

    $ docker service create --detach nginx:alpine
    280hjnzy0wzje5o56gr22a46n

Running against a 17.03 daemon, without specifying the `--detach` flag;

    $ docker service create nginx:alpine

Allow --detach and --quiet flags when using --rollback
Commit 78c204ef79 added
(f9bd8ec8b268581f93095c5a80679f0a8ff498bf in the moby repo)
a validation to prevent `--rollback` from being used
in combination with other flags that update the
service spec.

This validation was not taking into account that
some flags only affect the CLI behavior, and
are okay to be used when rolling back.

This patch updates the validation, and adds
`--quiet` and `--detach` to the list of allowed
flags.
