How to wait for pg_isready
It appears that there is no reliable way to run a shell command within the docker instance, other than using timeouts?
I'd like to implement WaitFor strategy such that the port is fully available to use, like
#[derive(Clone)]
struct PgIsReady();
#[async_trait]
impl WaitFor for PgIsReady {
async fn wait_for_ready(&self, container: PendingContainer) -> Result<RunningContainer, DockerTestError> {
// container
todo!()
}
}
but none of fields are public for PendingContainer
. Any ideas?
