Oracle Database 12.2 became available for download last week. This weekend I’ve been playing with Docker and created a container with it. The whole process is so easy, thanks to the work by Gerald Venzl at Oracle. You’ll find all the information you need in his blog post. Though the post is for version 188.8.131.52, the dockerfiles have already been updated for 184.108.40.206, and you can download it from Github using the link he provides in the post.
It takes sometime to create a container (depending on your hardware, of course), so when I discovered that the examples / demos that are distributed in another file were not included, I decided to try to add it to the running container. It is easy, just download the linuxx6412201examples.zip file and copy it into the running container, which in my case is named ora12.2:
docker cp linuxx6412201examples.zip ora12.2:/tmp
Also unzip a copy of the included response file locally:
unzip -j -d /tmp linuxx6412201examples.zip \ examples/response/demosinstall.rsp
Edit it and change the variables so they look like this:
UNIXGROUPNAME=oinstall ORACLEHOME=/opt/oracle/product/220.127.116.11/dbhome1 ORACLEBASE=/opt/oracle
Copy it to the container:
docker cp /tmp/demosinstall.rsp ora12.2:/tmp
Connect to your container with a command similar to this (again, ora12.2 is the name of my container):
docker exec -ti ora12.2 /bin/bash
Inside the container, unzip the transferred zip file and start the installation with:
cd /tmp unzip linuxx6412201examples.zip cd examples ./runInstaller -silent -force -waitforcompletion \ responsefile /tmp/demosinstall.rsp -ignoresysprereqs -ignoreprereq
You can now verify that you have more demos installed, for instance under $ORACLEHOME/md/demo.
Of course you can achieve the same effect by adding a few lines to the Dockerfile, build, and run again. Something like this should do for the Dockerfile:
Added install of examples ENV EXAMPLERSP="demosinstall.rsp" \ EXAMPLEFILE="linuxx6412201examples.zip" COPY $EXAMPLERSP $EXAMPLEFILE /tmp/ RUN cd /tmp && \ unzip linuxx6412201examples.zip && \ cd examples && \ ./runInstaller -silent -force -waitforcompletion \ -responsefile /tmp/demosinstall.rsp -ignoresysprereqs -ignoreprereq
It turned out to run just as fast since the new build builds on the previous images, oh well.
