that goes there
that goes there (hereafter "there" or there
) is:
- A library for general planning and execution of tasks on local and remote
hosts.
- crates.io
- Tasks are compiled down to
sh(1)
-compatible commands for execution. - Non-raw-command tasks attempt to validate prerequists before execution.
- A CLI for applying plans via:
- Local execution
- Remote SSH
- Agent-controller SSH
- An agent-controller pair for remote SSH execution.
Minimum supported Rust version: 1.66
features
Library:
- Tokio-based, fully-async
- Pluggable execution backends
- Local
- SSH
- Implement
Executor
yourself!
- Async log streaming
- Pluggable log streaming backends
- In-memory
- Implement
LogSource
/LogSink
yourself!
- Agent-controller shared IPC structs
- Plan validation
- Compile tasks down to
sh(1)
-compatible commands
- Compile tasks down to
- Host files + host groups
- Fully instrumented with
tracing::instrument
tracing
-based logging that can be consumed withtracing-subscriber
color_eyre
-based error reporting- Used to share error implementation between CLI/agent/controller
CLI:
- Log streaming by default
- Local execution
- SSH execution
- Agent-controller execution
- Plan validation
setup
Install pre-commit.
pre-commit install
pre-commit autoupdate
cargo install cargo-audit
usage
kinda undocumented for now. refer to test/*.yaml
for some plan/hostfile
examples.
todo
- Pretty tui with makeup for log streaming
show me something pretty
