* Update k8s sync docs
- remove docs that said for nodeport service we register each instance
on a node with its same node name. We instead register each instance
onto the k8s-sync node
- add docs describing which ports and ips are used
Related changes:
- hard-fail the xDS connection attempt if the envoy version is known to be too old to be supported
- remove the RouterMatchSafeRegex proxy feature since all supported envoy versions have it
- stop using --max-obj-name-len (due to: envoyproxy/envoy#11740)
This implements a solution for #7863
It does:
Add a new config cache.entry_fetch_rate to limit the number of calls/s for a given cache entry, default value = rate.Inf
Add cache.entry_fetch_max_burst size of rate limit (default value = 2)
The new configuration now supports the following syntax for instance to allow 1 query every 3s:
command line HCL: -hcl 'cache = { entry_fetch_rate = 0.333}'
in JSON
{
"cache": {
"entry_fetch_rate": 0.333
}
}
* Fix typos on commandline flags, updated config opts
- Added anchors to https://github.com/hashicorp/consul/pull/8223
- Fix Typos
Updated to include config file options as well as CLI.
Highlights:
- add new endpoint to query for intentions by exact match
- using this endpoint from the CLI instead of the dump+filter approach
- enforcing that OSS can only read/write intentions with a SourceNS or
DestinationNS field of "default".
- preexisting OSS intentions with now-invalid namespace fields will
delete those intentions on initial election or for wildcard namespaces
an attempt will be made to downgrade them to "default" unless one
exists.
- also allow the '-namespace' CLI arg on all of the intention subcommands
- update lots of docs
This example shows a TLS enabled ingress config on a non-https port.
Currently, that means we require the port to be specified in one of the
host entries to route traffic.
* Updates docs with ingress Host header changes
Clarify that a Host header is required for L7 protocols, and specify
that the default is to use the Consul DNS ingress subdomain
* Add sentence about using '*' by itself for testing
* Add optional step for using L7 routing config
* Note that port numbers may need to be added in the Hosts field
* Formatting spaces between keys in Config entries
* Service Router spacing
* Missing Camel Case proxy-defaults
* Remove extra spaces service-splitter
* Remove extra spsaces service-resolver
* More spaces a la hclfmt
* Nice!
* Oh joy!
* More spaces on proxy-defaults
* Update website/pages/docs/agent/config-entries/proxy-defaults.mdx

A Node Identity is very similar to a service identity. Its main targeted use is to allow creating tokens for use by Consul agents that will grant the necessary permissions for all the typical agent operations (node registration, coordinate updates, anti-entropy).
Half of this commit is for golden file based tests of the acl token and role cli output. Another big updates was to refactor many of the tests in agent/consul/acl_endpoint_test.go to use the same style of tests and the same helpers. Besides being less boiler plate in the tests it also uses a common way of starting a test server with ACLs that should operate without any warnings regarding deprecated non-uuid master tokens etc.
This allows the operator to disable agent caching for the http endpoint.
It is on by default for backwards compatibility and if disabled will
ignore the url parameter `cached`.
The DNS resolution will be handled by Envoy and defaults to LOGICAL_DNS. This discovery type can be overridden on a per-gateway basis with the envoy_dns_discovery_type Gateway Option.
If a service contains an instance with a hostname as an address we set the Envoy cluster to use DNS as the discovery type rather than EDS. Since both mesh gateways and terminating gateways route to clusters using SNI, whenever there is a mix of hostnames and IP addresses associated with a service we use the hostname + CDS rather than the IPs + EDS.
Note that we detect hostnames by attempting to parse the service instance's address as an IP. If it is not a valid IP we assume it is a hostname.
The doc says: "When the Connect injector is installed, the Connect sidecar is automatically added to all pods." But, it depends on the configuration, so I think it's better to say: "When the Connect injector is installed, the Connect sidecar can automatically added to all pods."
Based on work done in https://github.com/hashicorp/memberlist/pull/196
this allows to restrict the IP ranges that can join a given Serf cluster
and be a member of the cluster.
Restrictions on IPs can be done separatly using 2 new differents flags
and config options to restrict IPs for LAN and WAN Serf.
