CircleCI build failing normally, but passing locally and on SSH server

Here’s the Dockerfile that I’m using:

FROM ubuntu:trusty
FROM ruby:2.3.1

RUN apt-get update
RUN apt-get install -y \
  build-essential \
  libpq-dev imagemagick \
  libmagickwand-dev \
  libmagic-dev \
  python-pygments \
  ghostscript

ENV MYSQL_ROOT_HOST=%

COPY ./texlive-install.sh /root/texlive-install.sh
COPY ./texlive.profile /root/texlive.profile

RUN chmod +x ~/texlive-install.sh
RUN ~/texlive-install.sh

Here’s one of the latest builds:
https://circleci.com/gh/akashagarwal7/doubtfire-api/128

In the project we’re using texlive and a tool called lualatex to generate PDFs. However, one of the tests which does generate PDFs is failing when I trigger the build normally, but not when I run rake test locally or when SSH’d into the server. How can I fix this issue? Any help would be much appreciated.

There’s a few possible issues:

  • A server in your build is not ready to receive requests (e.g. MySQL)
  • Your failing build is missing env vars that you have in SSH

I notice also that your PostgreSQL image is commented out - is that deliberate?

Hey @halfer, thank you for replying.
MySQL is receiving and serving requests, that isn’t a problem.
I didn’t set anything new in the SSH environment, simply ran the tests using rake test.

Yup, PostgreSQL is supposed to be commented out for now.

How have you verified this?

No, but you probably have a .bash_profile or similar that sets things up for you (like PATH). I recommend looking at your build step logs to see what the error is.
