Chapter 11: ./e2e.sh is failing

Looks like postgres is exiting out. Please suggest

In such cases, to debug, check the logs for the service which is failing i.e. postgres.

docker-compose logs db

Root Cause:

The docker image for db is been updated in the repository by the authors of this docker image. Since then, its expecting you to either provide a password, or enable trust authentication ( Which is disabled by default).

To fix this, you would have to add POSTGRES_HOST_AUTH_METHOD var and set it to trust.

  db: 
    image: postgres:9.4
    volumes: 
      - db-data:/var/lib/postgresql/data
    environment: 
      POSTGRES_HOST_AUTH_METHOD: trust
 

This should fix failing postgres db container.

I just found a different error in the script, to solve it I made some changes to the script. When the script is executed for the first time the phantomjs script return <!-- , unfortunately bash can't store that string in a variable so I think the sed command was for that. After that I checked if the string is only digits, if not I assume there are no votes yet and assign 1 to current variable.

current=`phantomjs render.js "http://result:4000/" | grep -i vote | cut -d ">" -f 4 | cut -d " " -f1 | sed -e 's/\!//g'`
 
echo $current | grep -q -e "[0-9]\+"
if [[ $? -ne 0 ]]; then
  current=1
fi

These kinds of fixes should be added as hyperlinks somewhere on the proper lesson ... because searching for solutions to common problems here is very hard

Hi @donquijotedelasnubes , sometimes the issue is associated to the specific environment/shell that the person is using to make the tests. I haven't heard of this issue previously.

Regards,
Luis.
