# wait-for-oracle

A small Docker utility to check the availability or existence of tables and records in a dependent Oracle database, tested with [Oracle 11g](https://hub.docker.com/r/sath89/oracle-xe-11g/).

It uses maven, the OJDBC driver is included under the `driver` folder, to build just run `mvn package`.

To use in a project copy both, the jar file (the one that's not prefixed with `original-`) at the `target` folder and the bash script in the `bin` directory to a location in your project, add as entrypoint to your docker file among the lines of the supplied example.

```sh

usage: wait-for-oracle host user password command [-q query] [-d delay] [-e --exceptions]

 -c,--command    The command to run after the verification success.

 -d,--delay      The delay between tries.

 -e,--exceptions      Show the exception messages with the retry message.

 -h,--host       The JDBC connection string. iex:

                      jdbc:oracle:thin:@localhost:1521:xe

 -p,--pass       The database password.

 -q,--query      The query to verify the database integrity.

 -u,--user       The username for the databases.

```

Add in the docker file for example:

```dockerfile

    volumes:

      - ./docker/wait-for-oracle.jar:/wait-for-oracle.jar

      - ./docker/wait-for-oracle:/wait-for-oracle

    entrypoint: ["./wait-for-oracle", "-h", "jdbc:oracle:thin:@oracle:1521:xe", "-u", "system", "-p", "system", "-c", "\"java -Djava.security.egd=file:/dev/./urandom -jar /app.jar\""]

```

## TODO

* Still working in the README

* Handle args better in the script

* Default connection and credentials

* Maybe it doesn't actually need the bash script?
