Assuming you already have an ember-cli app. First, let's create a Dockerfile:
# Dockerfile
FROM node:10-alpine
RUN npm install -g ember-cli
RUN \
echo http://dl-3.alpinelinux.org/alpine/edge/main >> /etc/apk/repositories && \
apk add chromium
WORKDIR /myapp
COPY . /myapp/
RUN yarn
CMD ["ember", "test"]
Then you will need to alter your application testem.js. Note that we are not using Chrome, but Chromium:
module.exports = {
test_page: 'tests/index.html?hidepassed',
disable_watching: true,
launch_in_ci: [
'Chromium'
],
launch_in_dev: [
'Chromium'
],
browser_args: {
Chromium: {
ci: [
// --no-sandbox is needed when running Chrome inside a container
// process.env.CI ? '--no-sandbox' : null,
'--no-sandbox',
'--headless',
'--disable-gpu',
'--disable-dev-shm-usage',
'--disable-software-rasterizer',
'--mute-audio',
'--remote-debugging-port=0',
'--window-size=1440,900'
].filter(Boolean)
}
}
};
Build your container:
$ docker build -t myapp .
And after this your tests should be able to run:
$ docker run myapp
Could not start watchman

For me this fails with "Failed to read DnsConfig." I could only find this question but no solution: stackoverflow.com/questions/548383...
What do you do for watchman? Is there concern on file size of image with chromium installed?
If there is a need for watchman, it is certainly possible to install it. Last time I checked Apline and Debian had quite straightforward installation.
The image sizes are nothing small TBH, but gives you the whole UI testing options. Storage space is cheap, so never considered that an issue.
