Adds info about `k8stag` and `nodePortSyncType` options that were
added in consul-helm v0.5.0.
Additionally moves the k8sprefix to match the order in the Helm chart
values file, while also clarifying that it only affects one sync
direction.
If a user installs the default Helm chart Consul on a Kubernetes
cluster that is open to the internet, it is lacking some important
security configurations.
* Re-worked the ACL guide into two docs and an updated guide.

This endpoint aggregates all checks related to <service id> on the agent
and return an appropriate http code + the string describing the worst
check.
This allows to cleanly expose service status to other component, hiding
complexity of multiple checks.
This is especially useful to use consul to feed a load balancer which
would delegate health checking to consul agent.
Exposing this endpoint on the agent is necessary to avoid a hit on
consul servers and avoid decreasing resiliency (this endpoint will work
even if there is no consul leader in the cluster).
* Adding the new backup guide
* Update website/source/docs/guides/backup.html.md
Looks good.

* Added a link to the deployment guide, but needed to remove a sentence referring to a guide that's not published yet.
* fixed typo
This changes with time so will opt to not hardcoding this. Investigated using the middleman helper to render
out the current configured version but that won't exist on learn.hashicorp.com so I think this
is the most future-proof way.

Some redirects are not possible with a redirect file, so we send traffic to
learn.hashicorp.com with custom VCL (Varnish) handlers using the Fastly web
admin.
Future migrations of content to learn.hashicorp.com should also use this
approach.

There is a fine line between making the helm chart easy and simple to
use and supporting lots of configurability. This documents options for
users who would like to extend the Helm chart beyond what is readily
available in the `values.yaml` file.
This adds two Helm chart values into the documentation with details
that have come up in several issues.
Additionally, it notes that persistent volumes and their claims need
to be removed manually because of current kubernetes and helm design.

* Updated sidebar layout and deprecated warning
* Fix partial rendering in service command (CLI) help
* Fix sample JSON to be a valid json for service registration
* Add missing id field to make the complete document complete.
This field was added back into the helm chart, but it was not added
back to the documentation. This adds it, then additionally fixes a
few typos in the same file.
* Implement CLI token cloning & special ID handling
* Update a couple CLI commands to take some alternative options.
* Document the CLI.
* Update the policy list and set-agent-token synopsis
Based on info from consul-helm issue 16, the formatting of the helm
chart value for joining an external cluster needs to be specified
as a yaml array. This updates the documentation to reflect this.
This PR is almost a complete rewrite of the ACL system within Consul. It brings the features more in line with other HashiCorp products. Obviously there is quite a bit left to do here but most of it is related docs, testing and finishing the last few commands in the CLI. I will update the PR description and check off the todos as I finish them over the next few days/week.
Description
At a high level this PR is mainly to split ACL tokens from Policies and to split the concepts of Authorization from Identities. A lot of this PR is mostly just to support CRUD operations on ACLTokens and ACLPolicies. These in and of themselves are not particularly interesting. The bigger conceptual changes are in how tokens get resolved, how backwards compatibility is handled and the separation of policy from identity which could lead the way to allowing for alternative identity providers.
On the surface and with a new cluster the ACL system will look very similar to that of Nomads. Both have tokens and policies. Both have local tokens. The ACL management APIs for both are very similar. I even ripped off Nomad's ACL bootstrap resetting procedure. There are a few key differences though.
Nomad requires token and policy replication where Consul only requires policy replication with token replication being opt-in. In Consul local tokens only work with token replication being enabled though.
All policies in Nomad are globally applicable. In Consul all policies are stored and replicated globally but can be scoped to a subset of the datacenters. This allows for more granular access management.
Unlike Nomad, Consul has legacy baggage in the form of the original ACL system. The ramifications of this are:
A server running the new system must still support other clients using the legacy system.
A client running the new system must be able to use the legacy RPCs when the servers in its datacenter are running the legacy system.
The primary ACL DC's servers running in legacy mode needs to be a gate that keeps everything else in the entire multi-DC cluster running in legacy mode.
So not only does this PR implement the new ACL system but has a legacy mode built in for when the cluster isn't ready for new ACLs. Also detecting that new ACLs can be used is automatic and requires no configuration on the part of administrators. This process is detailed more in the "Transitioning from Legacy to New ACL Mode" section below.

* agent: always register pprof handlers and protect
This will allow us to avoid a restart of a target agent
for profiling by always registering the pprof handlers.
Given this is a potentially sensitive path, it is protected
with an operator:read ACL and enable debug being
set to true on the target agent. enable_debug still requires
a restart.
If ACLs are disabled, enable_debug is sufficient.
* command/debug: use trace.out instead of .prof
More in line with golang docs.
* agent: fix comment wording
* agent: wrap table driven tests in t.run()
In case `verify_server_hostname` is set in the configuration, Consul checks the certificate against `server.<datacenter>.<domain>`.
The name suggested by the guide generates errors like the following:
```
2018/10/10 12:42:20 [ERR] consul: Failed to confirm peer status for consul-3: rpc error getting client: failed to get conn: x509: certificate is valid for server.node.consul.labs, localhost, not server.consul.labs. Retrying in 16s...
```
Removing the `node` part from the certificate permits them to work also when that option is set.
* Add -enable-local-script-checks options
These options allow for a finer control over when script checks are enabled by
giving the option to only allow them when they are declared from the local
file system.
* Add documentation for the new option

* Add missing link
* Refactor Envoy guide into a separate guide and add bootstrap reference notes.
* Add limitations to Envoy docs; Highlight no fixes for known managed proxy issues on deprecation page; clarify snake cae stuff; Sidecar Service lifecycle
* Refactor Service Definition ProxyDestination.

* Document prepared query staleness quirk and force all background requests to AllowStale so we can spread service discovery load across servers.
In designing a potential UI for a configuration of `enable_tag_override`,
I found the documentation confusing and lengthy. Here, I've made an
attempt at re-writing this section to be more concise and clear.
I also made a few small changes to the organization of this file to map
explanations to the order of the properties listing at the top. I find
it easier to scan docs when explanations appear in the same order they
are listed at the top. For explanations that span multiple paragraphs, I
provided a subheading, which also helps in linking from other pages.
Finally, I removed a duplicated paragraph from the documentation.
* Fill in gaps in semaphore guide
* Update to match that values come back b64 encoded
* Add that the value needs to be decoded

* Clarify requirements for lock holders in semaphore guide
* Adds Deployment Guide and update links
* Fixes releases link
* Re-organisation of content
* Cuts down "deployment" doc (which should focus on Reference Architecture) by moving raft and performance tuning to the Server Performance page which already covers some of this.
* Moves backups from "deployment" doc (which should focus on Reference Architecture) to "deployment-guide"
* Cleans up some notes and add single DC diagram
* Removes old link to deployment guide from nav
* Corrects minor styling, formatting, and grammar
* website: initial Kubernetes section with Helm information
* website: extraConfig for clients
* website: add more helm fields
* website: document extraVolumes
* website: document Consul DNS
* website: fix typos and show example of downward API
Fixes: #4578
Prior to this fix if there was an error binding to ports for the DNS servers the error would be swallowed by the gated log writer and never output. This fix propagates the DNS server errors back to the shell with a multierror.
* Implementation of Weights Data structures
Adding this datastructure will allow us to resolve the
issues #1088 and #4198
This new structure defaults to values:
```
{ Passing: 1, Warning: 0 }
```
Which means, use weight of 0 for a Service in Warning State
while use Weight 1 for a Healthy Service.
Thus it remains compatible with previous Consul versions.
* Implemented weights for DNS SRV Records
* DNS properly support agents with weight support while server does not (backwards compatibility)
* Use Warning value of Weights of 1 by default
When using DNS interface with only_passing = false, all nodes
with non-Critical healthcheck used to have a weight value of 1.
While having weight.Warning = 0 as default value, this is probably
a bad idea as it breaks ascending compatibility.
Thus, we put a default value of 1 to be consistent with existing behaviour.
* Added documentation for new weight field in service description
* Better documentation about weights as suggested by @banks
* Return weight = 1 for unknown Check states as suggested by @banks
* Fixed typo (of -> or) in error message as requested by @mkeeler
* Fixed unstable unit test TestRetryJoin
* Fixed unstable tests
* Fixed wrong Fatalf format in `testrpc/wait.go`
* Added notes regarding DNS SRV lookup limitations regarding number of instances

* Rephrase docs
* Adds XL machine spec and notes on large deployments
* Clarifies machine sizes
* Fixes internal links within the document
* Moves datacenter size guidelines to "Single Datacenter" section
* Added log-file flag to capture Consul logs in a user specified file
* Refactored code.
* Refactored code. Added flags to rotate logs based on bytes and duration
* Added the flags for log file and log rotation on the webpage
* Fixed TestSantize from failing due to the addition of 3 flags
* Introduced changes : mutex, data-dir log writes, rotation logic
* Added test for logfile and updated the default log destination for docs
* Log name now uses UnixNano
* TestLogFile is now uses t.Parallel()
* Removed unnecessary int64Val function
* Updated docs to reflect default log name for log-file
* No longer writes to data-dir and adds .log if the filename has no extension
By default, the Consul agent listens on the local interface
at port 8500 for API requests. This change makes the API examples
using `curl` copy-pasteable for this default configuration.
* updates docs for agent options
trying to add a little more clarity to suggestion that folks should use
port 8302 for both LAN and WAN comms
* website: clarify language for serf wan port behavior
* New Providers added and updated vendoring for go-discover
* Vendor.json formatted using make vendorfmt
* Docs/Agent/auto-join: Added documentation for the new providers introduced in this PR
* Updated the golang.org/x/sys/unix in the vendor directory
* Agent: TestGoDiscoverRegistration updated to reflect the addition of new providers
* Deleted terraform.tfstate from vendor.
* Deleted terraform.tfstate.backup
Deleted terraform state file artifacts from unknown runs.
* Updated x/sys/windows vendor for Windows binary compilation
* Added explainations on how having a working configuration for Prometheus
Since Prometheus escapes by default query parameters, this paragraph explains
how having `format=prometheus` to be taken into account by prometheus.
* Rephrase Prometheus notes in documentation as requested by @pearkes
The GitHub repo for this library says that it is no longer maintained
and should not be used. The Ruby Diplomat library provides similar
functionality instead (and is already listed here).
The floating paragraph seems to need additional indentation to work correctly on the markdown parser middle man uses - GitHub got it right before in the preview but the website broke dumping the new config option inline.
Previous version of the documentation didn't mention this, which can
lead to confusion when experimenting with Connect. Many other features
of Consul work fine without `-dev` mode, but Connect needs certs in
order to proxy, which must be done with this flag or by generating certs
directly and passing them to Consul in configs.
The original snippet did not put the JSON output on its own line, which
made it look like it was part of the previous or next `curl` command.
This patch formats and highlights the command and output to appear as
they would in the terminal while also highlighting the multi-datacenter
elements of the output.
Original `discovery` snippet had a `curl` command that mentioned
multi-datacenter support. This removes part of the command that was
incorrect. It adds styling for the `dc2` section of the JSON output that
highlights the part of the query that relates to multiple data centers.
I was going to the public feedback on Connect-Native app integration and came across [this](https://twitter.com/relistan/status/1012263110403555329) thread. Added a few statements in the Connect-Native app integration page.
* website: add object-fit-image polyfill for ie compatibility
* website: make entire carousel cards linkable
* website: adjust hero background positioning
* website: responsive updates to the home hero
* website: update home hero js to work better with turbolinks
* website: a few font weight adjustments
* website: add an overlay to ui video
