Docker for Windows and docker-maven-plugin - "SSLException: Unrecognized SSL message, plaintext connection" error
There might be some configuration element under %HOME%.docker affecting the communication with docker-maven-plugin. Try to remove your %HOME%.docker folder and restart docker. After that, run the
oc login -u user https://url-to-openshift:port --insecure-skip-tls-verify
and
docker login -u user -p token url-to-private-registry
and then open the %HOME%.docker and if your file is like this:
{ "auths": { "url-to-private-registry": {} }, "credsStore": "wincred" }then remove the credsStore part because the spotify docker-maven-plugin doesn't support it.
Example:
{ "auths": { "url-to-private-registry": {} }}When you run the docker login again, it will generate the token again and you shouldn't have any authentication problem.
After the login, your %HOME%.docker\config.json will look like this:
{ "auths": { "url-to-private-registry": { "auth:" "token-that-docker-maven-plugin-needs-when-property-useConfigFile-is-true" } }}At least, it worked for me.
