## Issue Addressed
There was a [`VecDeque` bug](https://github.com/rust-lang/rust/issues/108453) in some recent versions of the Rust standard library (1.67.0 & 1.67.1) that could cause Lighthouse to panic (reported by `@Sea Monkey` on discord). See full logs below.
The issue was likely introduced in Rust 1.67.0 and [fixed](https://github.com/rust-lang/rust/pull/108475) in 1.68, and we were able to reproduce the panic ourselves using [@michaelsproul's fuzz tests](https://github.com/michaelsproul/lighthouse/blob/fuzz-lru-time-cache/beacon_node/lighthouse_network/src/peer_manager/fuzz.rs#L111) on both Rust 1.67.0 and 1.67.1.
Users that uses our Docker images or binaries are unlikely affected, as our Docker images were built with `1.66`, and latest binaries were built with latest stable (`1.68.2`). It likely impacts user that builds from source using Rust versions 1.67.x.
## Proposed Changes
Bump Rust version (MSRV) to latest stable `1.68.2`.

## Issue Addressed
The minimum supported Rust version has been set to 1.66 as of Lighthouse v4.0.0. This PR updates Rust to 1.66 in lcli Dockerfile.

## Issue Addressed
The release CI is currently broken due to the addition of the `protoc` dependency. Here's a failure of the release flow running on my fork: https://github.com/michaelsproul/lighthouse/actions/runs/3155541478/jobs/5134317334
## Proposed Changes
- Install `protoc` on Windows and Mac so that it's available for `cargo install`.
- Install an x86_64 binary in the Cross image for the aarch64 platform: we need a binary that runs on the host, _not_ on the target.
- Fix `macos` local testnet CI by using the Github API key to dodge rate limiting (this issue: https://github.com/actions/runner-images/issues/602).
## Issue Addressed
I think the antithesis is failing due to an OOM which may be resolved by updating the ubuntu image it runs on. The lcli build looks like it's failing because the image lacks the `libclang` dependency

## Issue Addressed
The lcli and antithesis docker builds are failing in unstable so bumping all the versions here
Co-authored-by: realbigsean <sean@sigmaprime.io>
## Issue Addressed
N/A
## Proposed Changes
Use stable version of ubuntu base image in dockerfile instead of using latest. This will help in narrowing down issues with docker images.
## Issue Addressed
Closes#2938
## Proposed Changes
* Build and publish images with a `-modern` suffix which enable CPU optimizations for modern hardware.
* Add docs for the plethora of available images!
* Unify all the Docker workflows in `docker.yml` (including for tagged releases).
## Additional Info
The `Dockerfile` is no longer used by our Docker Hub builds, as we use `cross` and a generic approach for ARM and x86. There's a new CI job `docker-build-from-source` which tests the `Dockerfile` without publishing anything.
## Issue Addressed
- Resolves#2778
## Proposed Changes
Updates docker images from Buster (10) to Bullseye (11), since Bullseye is [listed](https://www.debian.org/releases/) as the "current stable release".
## Additional Info
NA
## Issue Addressed
Resolves: #2087
## Proposed Changes
- Add a `Dockerfile` to the `lcli` directory
- Add a github actions job to build and push and `lcli` docker image on pushes to `unstable` and `stable`
## Additional Info
It's a little awkward but `lcli` requires the full project scope so must be built:
- from the `lighthouse` dir with: `docker build -f ./lcli/Dockerflie .`
- from the `lcli` dir with: `docker build -f ./Dockerfile ../`
Didn't include `libssl-dev` or `ca-certificates`, `lcli` doesn't need these right?
