felixctl

The command-line tool for Felix. It publishes to and reads from streams, reads, writes and watches cache keys, shows which broker owns each shard, works consumer groups and counters, creates, changes and deletes what the control plane manages, manages RBAC policies and role assignments, moves shards and drains brokers, and runs load tests.

brew install getfelix/tap/felixctl          # macOS or Linux, releases after 0.6.0-preview.2
cargo install felixctl --version 0.6.0-preview.8

felixctl context add local --brokers 127.0.0.1:5000 --tenant t1 \
    --token-file token.jwt --ca-file broker-cert.pem
felixctl pub orders 'hello'
felixctl sub orders --from earliest --count 10
felixctl cache get users alice
felixctl group poll orders billing
felixctl topology orders
felixctl stream create orders --shards 4 --replication 3
felixctl stream ls
felixctl bench latency orders

Each release also attaches prebuilt archives for Linux, macOS and Windows, with shell completions and man pages, to its GitHub release, and publishes a container image:

docker run --rm ghcr.io/getfelix/felixctl:0.6.0-preview.8 --help   # or podman run

Releases before 0.6.0-preview.2 are under ghcr.io/gabloe, the project's previous owner.

From a checkout, cargo install --path crates/tools/felixctl.

Every command prints readable text, or JSON with --json, and exits with a status that says what went wrong: 2 for bad arguments or settings, 3 when nothing could be reached, 4 when a broker or the control plane refused, 5 when something does not exist. Deletes and drains ask first on a terminal and need --yes anywhere else. felixctl help <command> shows each command's flags and examples.

Connection settings come from a named context in felixctl/config.toml under the platform config directory, overridden by FELIX_* variables, overridden by flags. The full guide is the felixctl page of the documentation.

How it is built

The data-plane commands (pub, sub, cache get|put|del|watch, group, counter, topology) use only felix-client's public API, which makes this crate a check that the API is enough to build tools on. The control-plane commands use the REST API. bench links felix-loadgen and runs its scenarios in process, so its numbers measure what the perf suite measures.

Unit tests cover argument parsing, every command's help text, context resolution and output formatting (cargo test -p felixctl --bins). tests/offline.rs runs the binary without a cluster. tests/cluster/ runs every command against brokers and a control plane started by felix-cluster; build the broker first (cargo build -p felix-broker-service --bin felix-broker).

Licensed AGPL-3.0-only, because bench links felix-loadgen. See LICENSING.md in the repository.
