@Yannig Could you please advise how to create a new docker images release?

[Yannig]

There is a problem with the current builder (Travis). I think it's a good time to create a new org for this project and move everything to a different place.

For the moment, I have pushed the image on my Docker registry. You can retrieve the image here:

docker pull yannig/oracledb_exporter:0.3.2
