On the servers they must have a certificate.
On the clients they just have to set verify_outgoing to true to attempt TLS connections for RPCs.
Eventually we may relax these restrictions but right now all of the settings we push down (acl tokens, acl related settings, certificates, gossip key) are sensitive and shouldn’t be transmitted over an unencrypted connection. Our guides and docs should recoommend verify_server_hostname on the clients as well.
Another reason to do this is weird things happen when making an insecure RPC when TLS is not enabled. Basically it tries TLS anyways. We should probably fix that to make it clearer what is going on.
The envisioned changes would allow extra settings to enable dynamically defined auth methods to be used instead of or in addition to the statically defined one in the configuration.
This mixin was a very thin mixin over the top of our listeners utility,
and we have been gradually preferring using the utility straight rather
than using the mixin. This commit removes the last places where we still
used the mixin, and also potentially the last few places where we
continued to use the old API for our listeners utility.
There are a couple of things in here.
First, just like auto encrypt, any Cluster.AutoConfig RPC will implicitly use the less secure RPC mechanism.
This drastically modifies how the Consul Agent starts up and moves most of the responsibilities (other than signal handling) from the cli command and into the Agent.
* 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
All commands which read config (agent, services, and validate) will now
print warnings when one of the config files is skipped because it did
not match an expected format.
Also ensures that config validate prints all warnings.
Right now this is only hooked into the insecure RPC server and requires JWT authorization. If no JWT authorizer is setup in the configuration then we inject a disabled “authorizer” to always report that JWT authorization is disabled.
The WithEventSource mixin was responsible for catching EventSource
errors and cleaning up events sources then the user left a Controller.
As we are trying to avoid mixin usage, we moved this all to an
`EventSource` component, which can clean up when the component is
removed from the page, and also fires an onerror event.
Moving to a component firing an onerror event means we can also remove
all of our custom computed property work that we were using previously
to catch errors (thrown when a service etc. is removed)
While upgrading servers to a new version, I saw that metadata of
existing servers are not upgraded, so the version and raft meta
is not up to date in catalog.
The only way to do it was to:
* update Consul server
* make it leave the cluster, then metadata is accurate
That's because the optimization to avoid updating catalog does
not take into account metadata, so no update on catalog is performed.
