Errors when running puppeteer with docker

[wburningham]

What are you trying to achieve?

I'm trying to run tests in Puppeteer in Docker. May just need to use more docker run flags or change something in the codeceptjs.json.

What do you get instead?

Here is the repo with my setup for reproducing the error.

From within that repo I run

docker run --net=host -v /Code/codecept-test:/tests codeception/codeceptjs

Which uses the codeception/codeceptjs docker image with ID 5bbce4c27fdb

and I get the following error

CodeceptJS directory has been found.
CodeceptJS v1.1.7
Using test root "/tests"

My first test file @feature_set_1 --
 ✖ "before each" hook: codeceptjs.before for "test something @one @example" in 47ms

Details

From within the docker image I pulled the following

• CodeceptJS version: v1.1.7
• NodeJS Version: v8.9.1
• Operating System: uname -a provides Linux linuxkit-025000000001 4.9.75-linuxkit-aufs #1 SMP Tue Jan 9 10:58:17 UTC 2018 x86_64 GNU/Linux
• Puppeteer version: whatever is install in the docker image
• Configuration file: link
• Suite config: link

I did a docker pull on the codeception/codeceptjs image and got id f976668debef The same error still occurs.

Any advice?

[wburningham]

I updated the helper section of my codecept config to pass the --no-sandbox arg and it seemed to work. What does this do and why is it required?

"helpers": {
    "Puppeteer": {
      "chrome":{
        "args": ["--no-sandbox"]
      }
    }
  },

I have the same issue with ImgID f976668debef. At this time used the same fix into config

@wburningham perhaps this will help explain https://www.google.com/googlebooks/chrome/med_26.html

Using the node:14 helped me to fix these problems.
