Subject ManifoldCF Docker MySQL Connection Error
Date Sat, 24 Nov 2018 12:27:59 GMT
Hi All,

I try to test ManifoldCF via docker. I've run mysql as follows:

docker run --name custom-mysql -v /home/ubuntu/mysql-conf:/etc/mysql/conf.d
-e MYSQL_ROOT_PASSWORD=mypass -d mysql:5.7.16

I've run my docker container of ManifoldCF as follows:

docker run --name manifoldcf --link custom-mysql:mysql -p 8345:8345 -it
manifoldcf:2.7.1

However, I get:

*org.apache.manifoldcf.core.interfaces.ManifoldCFException: Error getting
connection: Communications link failure*

*The last packet sent successfully to the server was 0 milliseconds ago.
The driver has not received any packets from the server.*

I can connect MySQL via command line, I can access it via another docker
container and I can access it if I create a project which just includes
ConnectionFactory.java of ManifoldCF.

What may be the reason for this?

Kind Regards,
