"Can not connect to Ryuk at localhost" on Fedora #4014
Description
I want to publish an issue with a connection to Ryuk and the solution which we found in Testcontainers Slack chat that this information will be possible to find.
When running my test, I get the following:
21:22:12.834 [testcontainers-ryuk] WARN org.testcontainers.utility.ResourceReaper - Can not connect to Ryuk at localhost:32776

You may have seen a similar log in this issue: #3166 . Whereas a solution, it was suggested to use a newly released version 1.15.0-rc2 (#3159). But it didn't work for me because I've already used the 1.15.3 version and what is more important it was a specific on MacOs only problem.
OS: Fedora 33
Docker version: 19.03.13
For Fedora (and probably on other Linux distros) user, it can be fixed if add the following line to the .testcontainers.properties
ryuk.container.privileged = true
The .testcontainers.properties file should be located (or already exist) by this way: /home/myuser/.testcontainers.properties.
You can find more information about .testcontainers.properties file at this link: https://www.testcontainers.org/features/configuration/

Since I answered my own question, I think that this issue can be closed. Not sure about labels for this issue but if necessary they can be added (I don't know how to do it).
