There is an undocumented way of mapping a dynamically allocated port to the container. This is applicable in bridge networking ( necessary for consul connect enabled services ) to expose the service *directly*. This is needed when using upstream connect services, but you need to expose the service by normal means. By referencing the current documentation you need to use static ports in order to do so. Introduced in #6189 but undocumented
You'd think since golangci-lint embeds misspell we could use that,
but it fails to run if it finds no Go source files, which is the
case in our website/ directory that we want to check.
gometalinter has been deprecated, with golangci-lint as its spiritual
and recommended successor. Here we switch to using it with an equivalent
configuration, albeit with newer versions of some linters.
To maintain compatibility with existing settings, we have a couple of
things disabled here, specifically:
- tests
We have a lot of unused code in our tests that choke deadcode.
We should attempt to clean these up soon so that we can lint our
testcode.
- govet.check-shadowing = false
This breaks on redefining `err` which we do all over the nomad
codebase.
When trying to run this example, Nomad v0.10.2 raises the following error:
`Error getting job struct: Error parsing job file from example-ipv6.hcl: error parsing: At 33:22: Unknown token: 27:16 IDENT db`
Adding quotes around the port map `db` fixes the problem and the job works as expected.
Update github.com/aws/aws-sdk-go and github.com/hashicorp/go-discover to
pick up support for EC2 Metadata Instance Service v2 changes.

Fixes#5856
When the scheduler looks for a placement for an allocation that's
replacing another allocation, it's supposed to penalize the previous
node if the allocation had been rescheduled or failed. But we're
currently always penalizing the node, which leads to unnecessary
migrations on job update.
This commit leaves in place the existing behavior where if the
previous alloc was itself rescheduled, its previous nodes are also
penalized. This is conservative but the right behavior especially on
larger clusters where a group of hosts might be having correlated
trouble (like an AZ failure).

Fixes#6787
In ProposedAllocs the proposed alloc slice was being copied while its
contents were not. Since RemoveAllocs nils elements of the proposed
alloc slice and is called twice, it could panic on the second call when
erroneously accessing a nil'd alloc.
The fix is to not copy the proposed alloc slice and pass the slice
returned by the 1st RemoveAllocs call to the 2nd call, thus maintaining
the trimmed length.
