Concatenate multiple YAML files into a single YAML stream and write it to stdout.
I built this to easily apply Kubernetes manifests in bulk.
ycat manifests/*.yaml | kubectl apply -f -
With a modern shell (e.g. zsh):
kubectl apply -f <(ycat manifests/*.yaml)
Save a bundled manifest for later use:
ycat manifest/*.yaml > release.yaml
ycat FILE [FILE ...]
The concatenated YAML stream is written to stdout and can be piped to another program or a file.
Requirements:
- Rust compiler (tested with >= 1.68.2, older versions will probably work too)
- Cargo
Run tests: cargo test
Build a debug binary: cargo build
Build a release binary: cargo build --release
Build and install to ~/.cargo/bin: cargo install --path=.
