This PR is based on the previous work by @snuggie12 in PR #6825. It adds the command consul intention list to list all available intentions. The list functionality for intentions seems a bit overdue as it's just very handy. The web UI cannot list intentions outside of the default namespace, and using the API is sometimes not the friendliest option. ;)
I cherry picked snuggie12's commits who did most of the heavy lifting (thanks again @snuggie12 for your great work!). The changes in the original commit mostly still worked on the current HEAD. On top of that I added support for namespaces and fixed the docs as they are managed differently today. Also the requested changes related to the "Connect" references in the original PRs have been addressed.
Fixes#5652

Extend Consul’s intentions model to allow for request-based access control enforcement for HTTP-like protocols in addition to the existing connection-based enforcement for unspecified protocols (e.g. tcp).
- Upgrade the ConfigEntry.ListAll RPC to be kind-aware so that older
copies of consul will not see new config entries it doesn't understand
replicate down.
- Add shim conversion code so that the old API/CLI method of interacting
with intentions will continue to work so long as none of these are
edited via config entry endpoints. Almost all of the read-only APIs will
continue to function indefinitely.
- Add new APIs that operate on individual intentions without IDs so that
the UI doesn't need to implement CAS operations.
- Add a new serf feature flag indicating support for
intentions-as-config-entries.
- The old line-item intentions way of interacting with the state store
will transparently flip between the legacy memdb table and the config
entry representations so that readers will never see a hiccup during
migration where the results are incomplete. It uses a piece of system
metadata to control the flip.
- The primary datacenter will begin migrating intentions into config
entries on startup once all servers in the datacenter are on a version
of Consul with the intentions-as-config-entries feature flag. When it is
complete the old state store representations will be cleared. We also
record a piece of system metadata indicating this has occurred. We use
this metadata to skip ALL of this code the next time the leader starts
up.
- The secondary datacenters continue to run the old intentions
replicator until all servers in the secondary DC and primary DC support
intentions-as-config-entries (via serf flag). Once this condition it met
the old intentions replicator ceases.
- The secondary datacenters replicate the new config entries as they are
migrated in the primary. When they detect that the primary has zeroed
it's old state store table it waits until all config entries up to that
point are replicated and then zeroes its own copy of the old state store
table. We also record a piece of system metadata indicating this has
occurred. We use this metadata to skip ALL of this code the next time
the leader starts up.
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
When node name contains vertical bar symbol some commands output is
garbled because `|` is used as a delimiter in `columnize.SimpleFormat`.
This commit changes format string to use `\x1f` - ASCII unit
separator[1] as a delimiter and also adds test to cover this case.
Affected commands:
* `consul catalog nodes`
* `consul members`
* `consul operator raft list-peers`
* `consul intention get`
Fixes#3951.
[1]: https://en.wikipedia.org/wiki/Delimiter#Solutions
* First conversion
* Use serf 0.8.2 tag and associated updated deps
* * Move freeport and testutil into internal/
* Make internal/ its own module
* Update imports
* Add replace statements so API and normal Consul code are
self-referencing for ease of development
* Adapt to newer goe/values
* Bump to new cleanhttp
* Fix ban nonprintable chars test
* Update lock bad args test
The error message when the duration cannot be parsed changed in Go 1.12
(ae0c435877d3aacb9af5e706c40f9dddde5d3e67). This updates that test.
* Update another test as well
* Bump travis
* Bump circleci
* Bump go-discover and godo to get rid of launchpad dep
* Bump dockerfile go version
* fix tar command
* Bump go-cleanhttp
This way we can avoid unnecessary panics which cause other tests not to run.
This doesn't remove all the possibilities for panics causing other tests not to run, it just fixes the TestAgent
