Seeing something similar in a Spring Boot project when upgrading to Spring Boot 3.2.1:

java.lang.RuntimeException: org.apache.hc.client5.http.HttpHostConnectException: Connect to unix://localhost:2375 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused

Same issue here. First reported on 21 Dec 2023. Docker Java is configured to use UNIX socket at unix://var/run/docker.sock, but since a while we started getting the error

org.apache.hc.client5.http.HttpHostConnectException: Connect to unix://localhost:2375 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused.

as if the UNIX socket docker host setting is ignored.

Update: downgrading to SpringBoot 3.1.6 has fixed the issues

As mentioned in spring-projects/spring-boot#38953 one of the reasons could be the bump of org.apache.httpcomponents.client5 in the recent SB release. As docker-java uses Apache http client library, the more recent v5.2.3 could be incompatible with the docker-java code.

Would it be possible to bump org.apache.httpcomponents.client5 to 5.2.3 and test it?

We just landed here because we upgraded spring boot plugin for Gradle to 3.2.1 and the world came crashing down in our build pipeline as a result of the new apache code pulled in.
