To create HammerDB docker image, we need to install docker first. As there are many documents on the Internet to describe how to install docker, I skip the installation step in this blog post.
Files to build the images
I created 3 files to build the image:
Dockerfile
We provide Dockerfile to docker to build the docker image. There are few existing HammerDB images in Docker Hub, but I don’t find one come with Oracle driver. Therefore, I take reference with HammerDB images in Docker Hub with my experience to install HammerDB with Oracle driver in Ubuntu to come up with this Dockerfile.
- Build the image with ubuntu:latest image
- Install curl, unzip and libaio library
- Download HammerDB 3.3 and install
- Download Oracle instant client 19.3 and install
- Copy load.tcl, load.sh to the image
- Run load.sh
load.tcl
- This is a HammerDB script to run timed TPC-C workload with 1, 2 and 3 virtual users. Schema and warehouse build is not included in this script.
load.sh
- This is a shell script called by the container, which replace the database user, password and easy connect string with the environment variables passed from the caller. It starts the hammerdbcli and call load.tcl
P.S. Oracle Easy Connect String, Username and Password are defined in environment variables which will be passed from the caller

Build the docker image
docker build –tag=hammerdb ./
Run the docker image
Run the docker image with load.sh script:
1
docker run -it --env SYSTEM_USER=system --env ORACLE_EZCONNECT=192.168.0.172:1521/orcl --env SYSTEM_PASSWORD=oracle hammerdb
Run the docker image with bash and call hammdbcli:
1
docker run -it --rm hammerdb /bin/bash
