Is it possible to use the --add-host option in pipeline docker image?

Is there a way to use the --add-host docker run option in the docker container specified in the image in a pipeline file? I want to be able to add entries the image's host file before running some e2e tests with testcafe. Thanks in advance.

@Jeremy Raymond this isn't currently possible. You can however add append entries to /etc/hosts as part of your build script:

echo "8.8.8.8 example.com" >> /etc/hosts

I had to use the following to get around permission being denied:

sudo -- sh -c "echo 8.8.8.8 example >> /etc/hosts"

But that seems to have done the trick. Thanks!

Hi @Jeremy Raymond . 

I had a similar need.

But this solution gave me the following result

- sh -c "echo 8.8.8.8 myserver >> /etc/hosts"
- cat /etc/hosts
- eval $(aws ecr get-login --region ${AWS_DEFAULT_REGION} --no-include-email)
- docker run -p 8080:8080 -d 000000000000.dkr.ecr.us-east-1.amazonaws.com/myserver-api:ci
- curl -vvv http://myserver:8080/myserver-api/path


Curl error message:

connect to 8.8.8.8 port 8080 failed: Operation timed out
Failed to connect to myserver port 8080: Operation timed out 

 

Is there some extra configuration in your solution you could share with me?

 

Thanks
