connect: support envoy 1.14.1 (#7624) 2020-04-09 20:58:22 +02:00
Daniel Nephin 575ad5c39f Fix CONSUL_HTTP_ADDR=https not enabling TLS
Use the config instead of attempting to reparse the env var.

Daniel Nephin 97c9f73261 Step 3: fix a bug in api.NewClient and fix the tests
The api client should never rever to HTTP if the user explicitly
requested TLS. This change broke some tests because the tests always use
an non-TLS http server, but some tests explicitly enable TLS.

Daniel Nephin ae42dea2d5 Step 2: extract the grpc address logic and a new type
The new grpcAddress function contains all of the logic to translate the
command line options into the values used in the template.

The new type has two advantages.

1. It introduces a logical grouping of values in the BootstrapTplArgs
   struct which is exceptionally large. This grouping makes the struct
   easier to understand because each set of nested values can be seen
   as a single entity.
2. It gives us a reasonable return value for this new function.

Daniel Nephin 5092aaf9b8 Step 1: move all the grpcAddr logic into the same spot
There is no reason a reader should have to jump around to find this value. It is only
used in 1 place

wan federation via mesh gateways (#6884)
This is like a Möbius strip of code due to the fact that low-level components (serf/memberlist) are connected to high-level components (the catalog and mesh-gateways) in a twisty maze of references which make it hard to dive into. With that in mind here's a high level summary of what you'll find in the patch:

There are several distinct chunks of code that are affected:

* new flags and config options for the server

* retry join WAN is slightly different

* retry join code is shared to discover primary mesh gateways from secondary datacenters

* because retry join logic runs in the *agent* and the results of that
  operation for primary mesh gateways are needed in the *server* there are
  some methods like `RefreshPrimaryGatewayFallbackAddresses` that must occur
  at multiple layers of abstraction just to pass the data down to the right
  layer.

* new cache type `FederationStateListMeshGatewaysName` for use in `proxycfg/xds` layers

* the function signature for RPC dialing picked up a new required field (the
  node name of the destination)

* several new RPCs for manipulating a FederationState object:
  `FederationState:{Apply,Get,List,ListMeshGateways}`

* 3 read-only internal APIs for debugging use to invoke those RPCs from curl

* raft and fsm changes to persist these FederationStates

* replication for FederationStates as they are canonically stored in the
  Primary and replicated to the Secondaries.

* a special derivative of anti-entropy that runs in secondaries to snapshot
  their local mesh gateway `CheckServiceNodes` and sync them into their upstream
  FederationState in the primary (this works in conjunction with the
  replication to distribute addresses for all mesh gateways in all DCs to all
  other DCs)

* a "gateway locator" convenience object to make use of this data to choose
  the addresses of gateways to use for any given RPC or gossip operation to a
  remote DC. This gets data from the "retry join" logic in the agent and also
  directly calls into the FSM.

* RPC (`:8300`) on the server sniffs the first byte of a new connection to
  determine if it's actually doing native TLS. If so it checks the ALPN header
  for protocol determination (just like how the existing system uses the
  type-byte marker).

* 2 new kinds of protocols are exclusively decoded via this native TLS
  mechanism: one for ferrying "packet" operations (udp-like) from the gossip
  layer and one for "stream" operations (tcp-like). The packet operations
  re-use sockets (using length-prefixing) to cut down on TLS re-negotiation
  overhead.

* the server instances specially wrap the `memberlist.NetTransport` when running
  with gateway federation enabled (in a `wanfed.Transport`). The general gist is
  that if it tries to dial a node in the SAME datacenter (deduced by looking
  at the suffix of the node name) there is no change. If dialing a DIFFERENT
  datacenter it is wrapped up in a TLS+ALPN blob and sent through some mesh
  gateways to eventually end up in a server's :8300 port.

* a new flag when launching a mesh gateway via `consul connect envoy` to
  indicate that the servers are to be exposed. This sets a special service
  meta when registering the gateway into the catalog.

* `proxycfg/xds` notice this metadata blob to activate additional watches for
  the FederationState objects as well as the location of all of the consul
  servers in that datacenter.

* `xds:` if the extra metadata is in place additional clusters are defined in a
  DC to bulk sink all traffic to another DC's gateways. For the current
  datacenter we listen on a wildcard name (`server.<dc>.consul`) that load
  balances all servers as well as one mini-cluster per node
  (`<node>.server.<dc>.consul`)

* the `consul tls cert create` command got a new flag (`-node`) to help create
  an additional SAN in certs that can be used with this flavor of federation.

xds: improve how envoy metrics are emitted (#6312)
Since generated envoy clusters all are named using (mostly) SNI syntax
we can have envoy read the various fields out of that structure and emit
it as stats labels to the various telemetry backends.

I changed the delimiter for the 'customization hash' from ':' to '~'
because ':' is always reencoded by envoy as '_' when generating metrics
keys.

Envoy CLI bind addresses (#6107)
* Ensure we MapWalk the proxy config in the NodeService and ServiceNode structs

This gets rid of some json encoder errors in the catalog endpoints

* Allow passing explicit bind addresses to envoy

* Move map walking to the ConnectProxyConfig struct

Any place where this struct gets JSON encoded will benefit as opposed to having to implement it everywhere.

* Fail when a non-empty address is provided and not bindable

* camel case

* Update command/connect/envoy/envoy.go

Fix envoy 1.10 exec (#5964)
* Make exec test assert Envoy version - it was not rebuilding before and so often ran against wrong version. This makes 1.10 fail consistenty.

* Switch Envoy exec to use a named pipe rather than FD magic since Envoy 1.10 doesn't support that.

* Refactor to use an internal shim command for piping the bootstrap through.

* Fmt. So sad that vscode golang fails so often these days.

* go mod tidy

* revert go mod tidy changes

* Revert "ignore consul-exec tests until fixed (#5986)"

This reverts commit 683262a6869033cb79e68fa1dba0f9ea83e9187d.

R.B. Boyer 4427417140 cli: avoid passing envoy bootstrap configuration as arguments (#4747)
Play a trick with CLOEXEC to pass the envoy bootstrap configuration as
an open file descriptor to the exec'd envoy process. The file only
briefly touches disk before being unlinked.

We convince envoy to read from this open file descriptor by using the
/dev/fd/$FDNUMBER mechanism to read the open file descriptor as a file.

Because the filename no longer has an extension envoy's sniffing logic
falls back on JSON instead of YAML, so the bootstrap configuration must
be generated as JSON instead.
