I’m trying to follow through labs/developer-tools/java/chapters/ch11-bigdata.adoc at master · docker/labs · GitHub this one and GitHub - fabianenardon/hadoop-docker-demo: A sample application with hadoop and docker sample requires io.fabric8:docker-maven-plugin to work which wants docker port to be available to connect.
export DOCKER_HOST="tcp://0.0.0.0:2375"
after that
mvn clean install -Papp-docker-image
and it throws
Cannot create docker access object : Cannot extract API version from server http://0.0.0.0:2375: Connect to 0.0.0.0:2375 [/0.0.0.0] failed: Connection refused (Connection refused) ->
Docker desktop created no dockerd and
{"hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]}
this won’t do the job either
sudo netstat -lntp | grep docker
returns ebuzer@DONE:~/git/docker hands on lab/hadoop-docker-demo/sample$ sudo netstat -lntp | grep docker tcp 0 0 0.0.0.0:37693 0.0.0.0:* LISTEN 6802/com.docker.bac
when i set
export DOCKER_HOST="tcp://0.0.0.0:37693"
and then
mvn clean install -Papp-docker-image
it returns
Cannot create docker access object : Cannot extract API version from server http://0.0.0.0:37693: 0.0.0.0:37693 failed to respond -> [Help 1]
I search the internet and they say click expose daemon option in settings but my version doesn’t have it.

Docker needs to test their own documentation examples with new code so that there will be no regression like this one.
