Could not find valid docker environment on Unix/Azure when upgrading from 1.17.6 to 1.18.x

[poorSock]

Hi,

I am a tester and using an azure pipeline to run tests. A selenium container gets started for that purpose.

Everything works fine with version 1.17.6
When upgrading to 1.18.0 or 1.18.1 I get following errors, no other changes on my codebase or the environment were made

docker daemon & client API versions seem to be 1.4.2

Thanks for the report... are you using docker-java in your build tool? try to use version 3.3.0. I can identify the error in your logs

failed with exception NoClassDefFoundError (com/github/dockerjava/api/command/LoadImageAsyncCmd). Root cause ClassNotFoundException (com.github.dockerjava.api.command.LoadImageAsyncCmd)

You can run mvn dependency:tree or ./gradlew dependencies

Thanks so much, I guess you meant 3.3.0
WebdriverManager still had the old ones
