The guide currently uses node, service, and service for the UI Policy.
This will cause a practically useless UI. This patch uses the _prefix
variants instead which will have the intended behavior.
It appears that the `read` command for ACL policies was used to template the `read` command for ACL tokens, and an invalid option was not dropped from the docs.
Given a query like:
```
{
"Name": "tagged-connect-query",
"Service": {
"Service": "foo",
"Tags": ["tag"],
"Connect": true
}
}
```
And a Consul configuration like:
```
{
"services": [
"name": "foo",
"port": 8080,
"connect": { "sidecar_service": {} },
"tags": ["tag"]
]
}
```
If you executed the query it would always turn up with 0 results. This was because the sidecar service was being created without any tags. You could instead make your config look like:
```
{
"services": [
"name": "foo",
"port": 8080,
"connect": { "sidecar_service": {
"tags": ["tag"]
} },
"tags": ["tag"]
]
}
```
However that is a bit redundant for most cases. This PR ensures that the tags and service meta of the parent service get copied to the sidecar service. If there are any tags or service meta set in the sidecar service definition then this copying does not take place. After the changes, the query will now return the expected results.
A second change was made to prepared queries in this PR which is to allow filtering on ServiceMeta just like we allow for filtering on NodeMeta.
* Support rate limiting and concurrency limiting CSR requests on servers; handle CA rotations gracefully with jitter and backoff-on-rate-limit in client
* Add CSR rate limiting docs
* Fix config naming and add tests for new CA configs

* missed some clusters
* updated three broken links for the sidebar nav
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.

This changes with time so will opt to not hardcoding this. Investigated using the middleman helper to render

is the most future-proof way.

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.

* Removes redirect from sample web.json demo file
* Removed typo
* 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

few typos in the same file.

* 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.

* command/debug: improve comment on metrics sleep
* command/debug: clarify usage
* 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.

≈
