Also of note is that for enterprise builds we can set CONSUL_NO_WEBSITE_UPDATE to prevent updating the version twice.
Lastly we also do not update the website version for pre-releases like rc1.
This just streamlines a release build a bit.
This PR is almost a complete rewrite of the ACL system within Consul. It brings the features more in line with other HashiCorp products. Obviously there is quite a bit left to do here but most of it is related docs, testing and finishing the last few commands in the CLI. I will update the PR description and check off the todos as I finish them over the next few days/week.
Description
At a high level this PR is mainly to split ACL tokens from Policies and to split the concepts of Authorization from Identities. A lot of this PR is mostly just to support CRUD operations on ACLTokens and ACLPolicies. These in and of themselves are not particularly interesting. The bigger conceptual changes are in how tokens get resolved, how backwards compatibility is handled and the separation of policy from identity which could lead the way to allowing for alternative identity providers.
On the surface and with a new cluster the ACL system will look very similar to that of Nomads. Both have tokens and policies. Both have local tokens. The ACL management APIs for both are very similar. I even ripped off Nomad's ACL bootstrap resetting procedure. There are a few key differences though.
Nomad requires token and policy replication where Consul only requires policy replication with token replication being opt-in. In Consul local tokens only work with token replication being enabled though.
All policies in Nomad are globally applicable. In Consul all policies are stored and replicated globally but can be scoped to a subset of the datacenters. This allows for more granular access management.
Unlike Nomad, Consul has legacy baggage in the form of the original ACL system. The ramifications of this are:
A server running the new system must still support other clients using the legacy system.
A client running the new system must be able to use the legacy RPCs when the servers in its datacenter are running the legacy system.
The primary ACL DC's servers running in legacy mode needs to be a gate that keeps everything else in the entire multi-DC cluster running in legacy mode.
So not only does this PR implement the new ACL system but has a legacy mode built in for when the cluster isn't ready for new ACLs. Also detecting that new ACLs can be used is automatic and requires no configuration on the part of administrators. This process is detailed more in the "Transitioning from Legacy to New ACL Mode" section below.
Adds additional 'enterprise' text underneath the 'startup' logo if the
ui is built with a CONSUL_BINARY_TYPE environment variable that doesn't
equal `oss`.
make XC_OS=linux XC_ARCH=amd64 when running on macos puts its binaries in ${GOPATH}/bin/linux_amd64/consul and not ${GOPATH}/bin/consul
This makes the build pull the binary from the right location.
1. Prints the $version that you are passing through to the docker
container
2. Prints the CONSUL_VERSION that is used in the UI v2 footer
3. Additionally added a `mkdir -p` so so `make ui-docker` runs with a
clean exit if run in isolation
We verify the git remote/url with whoever is running (in addition to other automated checks)
We also now run consul agent -dev, check is first 25 lines of output, consul info output and that consul leave works.
Improvements:
- More modular
- Building within docker doesn’t use volumes so can be run on a remote docker host
- Build containers include only minimal context so they only rarely need to be rebuilt and most of the time can be used from the cache.
- 3 build containers instead of 1. One based off of the upstream golang containers for building go stuff with all our required GOTOOLS installed. One like the old container based off ubuntu bionic for building the old UI (didn’t bother creating a much better container as this shouldn’t be needed once we completely remove the legacy UI). One for building the new UI. Its alpine based with all the node, ember, yarn stuff installed.
- Top level makefile has the ability to do a container based build without running make dist
- Can build for arbitrary platforms at the top level using: make consul-docker XC_OS=… XC_ARCH=…
- overridable functionality to allow for customizations to the enterprise build (like to generate multiple binaries)
- unified how we compile our go. always use gox even for dev-builds or rather always use the tooling around our scripts which will make sure things get copied to the correct places throughout the filesystem.
