docker-oracle-client

A docker-container for Oracle Instant Client 12, based on CentOs. Perfect for using together with a dockerized oracle database, for instance this one.

Step 1

Unfortunately, Oracle does not allow us to include their software in docker-images, so you need to download Oracle Instant Client linux binaries (and accept their license) before we build the image.

Get the following files

oracle-instantclient12.1-basic-12.2.0.1.0-1.x86_64.rpm
oracle-instantclient12.1-devel-12.2.0.1.0-1.x86_64.rpm
oracle-instantclient12.1-sqlplus-12.2.0.1.0-1.x86_64.rpm

from here

Place the files in the same directory as the Dockerfile.

Step 2 (optional)

Edit the included tnsnames.ora file, so you can conveniently access these databases from the container, without having to enter the entire connection string.

Step 3

Build the image

docker build -t oracle/oracleclient .

Step 4

Run the image. If you are running a dockerized database, pass its reference in via a docker link:

docker run -it --name oracleclient --link oracle:oracle oracle/oracleclient

Otherwise, you can run it without the link, and connect to other databases via a connection string.

docker run -it --name oracleclient oracle/oracleclient

Step 5

Verify that it works
