# Wait for `psql`

`wait-for-psql` is a simple script packed in a `Dockerfile` to wait for a

postgres database to become available. For instance, this is handy when

automatically testing a database schema, that takes some time to setup.

The Docker image is available at `bwibo/wait-for-psql` from

[DockerHub](https://hub.docker.com/repository/docker/bwibo/wait-for-psql/tags).

    docker run --rm -t bwibo/wait-for-psql \

      TIMEOUT HOST PORT DBNAME USERNAME PASSWORD [COMMAND] [ARGUMENTS...]

    TIMEOUT         Timeout in seconds

    HOST            Host or IP of the postgres server

    PORT            Postgres server port
