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.
* Adds redirects for Getting Started pages
* Uses correct links to resources at learn.hashicorp
* Reconfigures "Learn more" links to point to learn.hashicorp
* Links to learn.hashicorp on segmentation page
* Adds redirect for sample config file
* Fixes links to Getting Started guide on learn.hashicorp
* Remove getting started guide which is now on learn.hashicorp
* Corrects link to `consul/io` which should go to `consul.io`
* Revert "Remove getting started guide which is now on learn.hashicorp"
This reverts commit 2cebacf402f83fb936718b41ac9a27415f4e9f21 so a placeholder
message can be written here while we are transitioning content to
learn.hashicorp
* Adding a new page for getting started to direct users to learn.
* Added a note at the being of each doc to notify users about the temporary repo change.
* Revert "Added a note at the being of each doc to notify users about the temporary repo change."
This reverts commit 9a2a8781f9705028e4f53f758ef235e74b2b7198.
From conversation at https://github.com/hashicorp/consul/pull/4878
* 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
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/debug: add package for debugging, host info
* api: add v1/agent/host endpoint
* agent: add v1/agent/host endpoint
* command/debug: implementation of static capture
* command/debug: tests and only configured targets
* agent/debug: add basic test for host metrics
* command/debug: add methods for dynamic data capture

* command/debug: timing, wg, logs to disk
* vendor: add gopsutil/disk
* command/debug: add a usage section
* website: add docs for consul debug
* agent/host: require operator:read
* api/host: improve docs and no retry timing
* command/debug: fail on extra arguments
* command/debug: fixup file permissions to 0644
* command/debug: remove server flags
* command/debug: improve clarity of usage section
* api/debug: add Trace for profiling, fix profile
* command/debug: capture profile and trace at the same time
* command/debug: add index document
* command/debug: use "clusters" in place of members
* command/debug: remove address in output
* 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.
* Add documentation for the new option
* Nitpick doc wording
* Initial draft of Sidecar Service and Managed Proxy deprecation docs
* Service definition deprecation notices and sidecar service
* gRPC and sidecar service config options; Deprecate managed proxy options
* Envoy Docs: Basic envoy command; envoy getting started/intro
* Remove change that snuck in
* Envoy custom config example
* Add agent/service API docs; deprecate proxy config endpoint
* Misc grep cleanup for managed proxies; capitalize Envoy
* Updates to getting started guide
* 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
