Docker Compose is a very useful application which allows us to connect several containers together using minimal commands, or when we need to run several containers together which depend on each other. ![]() It’s not quite a bash script so please read it carefully and don’t just copy/paste every line into your terminal. Install Docker Compose As an additional step, we will install Docker Compose. If you’re reading this after May 2018, be sure to check the version numbers and do let me know if I need to update this or if you’ve spotted an improvement. Last week I finally dug in (and read the docs) and I wanted to share how I ultimately got it working (mostly for when I have to do this again). Setting up Docker on a Centos VM behind the corporate firewall and using a proxy to access the internet has proven to be trickier than we expected. So we decided to setup a stand-alone Docker image of Selenium Chrome that we could use to run our tests as part of our CD pipeline. One advantage of building an internal app is that we can support a small number of browsers (in this case Chrome). While there are some great cloud-based cross-browser testing tools out there, this team is building an internal app locked away behind the corporate firewall and every one of our virtual machines (VMs) uses a proxy to access the big scary internet and we couldn’t get the company’s preferred cloud-based tool to access our test environment. Set: CentOS 7 installed docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin running docker Try: docker-compose -env-file config.env up -build Got: docker-compose -env-file config.env up -build Define and run multi-container applications with Docker. I’ve been helping a team to improve its Continuous Delivery pipeline and as part of this work, we’re introducing BDD-style test automation using Serenity.
