Recently, we started using Elasticsearch to make locations search fast.

Now our search specs are dependent on Elasticsearch. We also added feature/system specs for it. To run feature/system specs, we need Chrome and Chromedriver software packages in our system.

I was working on setting up Elasticsearch, Chrome, and Chromedriver software packages on Drone CI. Let’s discuss how to set up those software packages and make them ready to serve.

Initially, I went through Drone docs and was able to set up Elasticsearch quickly using this example. But I was not able to find useful information for installing Chrome and Chromedriver software packages. Tried some docker images, but not able to make them work.

After investigating, I manually installed Chrome and Chromedriver packages using commands. Please check following Drone CI code .drone.yml and this might help you.

After these changes, our CI build passed successfully! 🚀

Found that Chrome installation takes a bit more time. But not sure if Chrome docker image solves this issue, if it does, I will recommend using that one.

It would be good if anyone knows useful references for installing these software packages using docker images and making them work, please do let me know.

Happy CI-ing!
