Fixes#2742
Previously the docs didn't clarify that if a server restarts as a client then force-leave won't lead to removing the node from the raft config. This is because the node, which is alive after a restart, will refute messages about it having left . These messages about members leaving are in turn what trigger Consul's leader to remove a server from raft.
Fixes: #5396
This PR adds a proxy configuration stanza called expose. These flags register
listeners in Connect sidecar proxies to allow requests to specific HTTP paths from outside of the node. This allows services to protect themselves by only
listening on the loopback interface, while still accepting traffic from non
Connect-enabled services.
Under expose there is a boolean checks flag that would automatically expose all
registered HTTP and gRPC check paths.
This stanza also accepts a paths list to expose individual paths. The primary
use case for this functionality would be to expose paths for third parties like
Prometheus or the kubelet.
Listeners for requests to exposed paths are be configured dynamically at run
time. Any time a proxy, or check can be registered, a listener can also be
created.
In this initial implementation requests to these paths are not
authenticated/encrypted.
The fields in the certs are meant to hold the original binary
representation of this data, not some ascii-encoded version.
The only time we should be colon-hex-encoding fields is for display
purposes or marshaling through non-TLS mediums (like RPC).
- fix instructions for CoreDNS (it updated)
- fix instructions for new component names
- recommend installing with the name 'consul'
- add disclaimer that catalog sync is not always required
- clean up example values.yaml files
* website: Update middleman-hashicorp container and Gemfile.lock
Time marches on, and so do security vulnerabilities in Nokogiri. So it's time
for a new container.
As with last time, here's a reminder for the next person who needs to update
this:
- You shouldn't just update the dependency in Gemfile.lock, because your build
times will go to heck as you compile Nokogiri from source on every run. So you
need an updated container with all the dependencies.
- To update the container, you need to push a new tag to the middleman-hashicorp
repo. Teamcity does the rest, and will ship a new container to Docker Hub
(unless its credentials are out of date, in which case go ask team-eng-serv.)
- Once that's pushed:
- Update Makefile
- Update the Gemfile
- Delete Gemfile.lock
- `make website` until it comes up, then ctrl-C
- Commit the changes
* website: Specify a different json version in Gemfile.lock
The Consul website uses different containers for preview and deploy, and this
oddball JSON version was causing issues. This commit sacrifices a little bit
of preview startup speed for (hopefully) working deploys.
- Bootstrap escape hatches are OK.
- Public listener/cluster escape hatches are OK.
- Upstream listener/cluster escape hatches are not supported.
If an unsupported escape hatch is configured and the discovery chain is
activated log a warning and act like it was not configured.
Fixes#6160
* website: update the vs. envoy and proxies page
This is the second result on Google for "consul envoy" and
it seemed like it needed a bit of an upgrade to help clarify the
current state.
