Oracle image configuration

An Oracle custom image includes the following configuration.

Create Custom Image panel

Image Reference

In the Image Reference field, provide the image reference for this image.

The image reference value must follow the Open Container Specification addressable image format:

[<registry>/][<project>/]<image>[:<tag>|@<digest>]

The image reference is a path that identifies the image and where it is located.

Container data mount path

In the Container Data Mount Path field, provide the path in the container to the database's data directory.

Database connection information

These settings provide connection information for databases that are created from the image:

1. Port - The port to use for connections to a database created from this image.

2. Data directory group - The Linux group identifier to mount the data directory of the database as.

3. Database username - The admin user for the database that is created by this image. Ephemeral uses this to create a non-admin user and a pluggable database, and to interact with the database in general.

4. Password environment variable - The name of the environment variable to set on the database container, to configure the password for the admin user, which is defined in the Database username field.

Initial database configuration

You specify whether the image automatically creates an initial database on startup, and provide the name of the initial database. If the image does not automatically create an initial database on startup, then Ephemeral uses the provided name to create the initial database.

1. By default, Ephemeral assumes that the image creates an initial database on startup, and Contains initial database is toggled to the on position. If the image does not create an initial database on startup, then toggle Contains initial database to the off position.

2. In the Initial database name field, provide the name of the initial database. If the image already contains an initial database, then this name must match the name of that database. If the image does not contain an initial database, then Ephemeral uses the name to create the initial database.

Minimum storage

In the Minimum storage field, enter the minimum storage in GB that is required for databases that are created from this image.

Maximum password length

When you start a database from this image, Ephemeral automatically generates a password for the database user.

In the Max password length field, type the maximum length for the password.

Oracle DBA privilege

In the Oracle DBA Privilege field, provide the name of the database role that the database user assumes when it connects to the database.

Oracle schema

In the Oracle Schema field, provide the name of the schema for the database.

Custom environment variables

You can also provide values for any additional environment variables.

Under Custom Environment Variables, to add a variable:

1. Click Add custom environment variable.

2. In the Name field for the variable, type the name of the variable.

3. In the Value field, type the value for the variable

To remove an environment variable, click its delete icon.
