Waits until all provided host and port pairs are opened. It is written using async rust.
There are currently two way how to install the app.
You can install the binary only with a minimal subset of features.
bash
cargo install wait-for-them
Or you can install it with all its features (including the nice progressbars).
bash
cargo install wait-for-them --all-features
bash
wait-for-them host1:port1 host2:port2
wait-for-them -t 5000 host1:port1 host2:port2
Note that it returns a number of unopened host:port combinations.
So if it worked ok it returns standard 0
.
wait-for-them host1:port1 host2:port2 -- cmd arg1 arg2
Note that if the ports are opened it returns the status code of cmd.
The main motivation of this program was to use it within docker-compose
config file (see docker-compose.yml
).
To support waiting for multiple hostname:port records in parallel.
