I had a really weird problem today deploying to production using mup. After deployment the docker container was reseting itself every 30 seconds or so. Alarm! Achtung!
After inspecting the container with docker logs containerName I've been able to conclude that the problem was due to two node packages: bcrypt and unicode.
I've solved the first problem removing the bcrypt node package. It's not optimal but at least it's working because meteor already provides a slower but fully functional bcrypt package.
The second problem with Unicode was really weird. This is the log:
make: Entering directory '/bundle/bundle/programs/server/npm/node\_modules/buffertools/build' CXX(target) Release/obj.target/buffertools/buffertools.o SOLINK\_MODULE(target) Release/obj.target/buffertools.node COPY Release/buffertools.node make: Leaving directory '/bundle/bundle/programs/server/npm/node\_modules/buffertools/build' \> firstname.lastname@example.org postinstall /bundle/bundle/programs/server/npm/node\_modules/unicode \> node install.js try to read file /usr/share/unicode/UnicodeData.txt … /usr/share/unicode/UnicodeData.txt not found. try to read file /usr/share/unicode-data/UnicodeData.txt … /usr/share/unicode-data/UnicodeData.txt not found. try to read file UnicodeData.txt … UnicodeData.txt not found. try to download … GET unicode.org:80/Public/UNIDATA/UnicodeData.txt
It looked like the package couldn't get the unicode data from unicode.org. I was able to install the package in my local machine so I'm afraid this problem can be related to my server being blocked (not sure why).
What I did to solve it was to log in to the docker machine and install the unicode data using the package manager:apt-get install unicode-data and that solved the issue since npm is smart enough to not request that data if it's already present in the system.
I know both solutions are actually hacks but I have my client's website working again and now I have time to think about those errors more carefully and try to find the root of the problem. I will probably add the apt-get command to my docker image but I am not sure why all of a sudden bcrypt has stopped working (I have not updated the bcrypt recently).
