To illustrate this, we will use a Hive and Hadoop environment, containing 5 Docker Containers from – https:\/\/github.com\/mesmacosta\/docker-hive.
\nSince I am on windows, I use Github desktop.<\/p>\n
Launch Github desktop and then go to File >> Clone Repository >> URL.<\/p>\n
![\"\"](\"https:\/\/qbytes.cloud\/wp-content\/uploads\/2021\/09\/clone1.png\")
<\/a><\/p>\nGo to https:\/\/github.com\/mesmacosta\/docker-hive – Click on Code > Copy. Paste URL into Github Desktop. Click Clone.<\/p>\n
![\"\"](\"https:\/\/qbytes.cloud\/wp-content\/uploads\/2021\/09\/clone2-1024x269.png\")
<\/a><\/p>\nNow open command prompt or Powershell – AS ADMINISTRATOR – and go to the directory where the docker files are located. In my case its in Documents > Github > docker-hive.<\/p>\n
Now let’s start up those containers:<\/p>\n
\n# docker-compose up -d\n<\/pre>\nNote: If you receive this error:
\nError response from daemon: Ports are not available: listen tcp 0.0.0.0:50070: bind: An attempt was made to access a socket in a way forbidden by its access permissions.<\/p>\n
Run this in command prompt or PS:<\/p>\n
\nnet stop winnat\nnet start winnat\n<\/pre>\nWe can see 5 containers:<\/p>\n

\n>docker network ls\nNETWORK ID NAME DRIVER SCOPE\n234dbbb8d381 bridge bridge local\nd438c2ba7c56 docker-hive_default bridge local\ne284120f22c7 host host local\n019daa8ddd49 none null local\n<\/pre>\nBy default docker compose sets up a single network for your app. And your app\u2019s network is given a name based on the \u201cproject name\u201d, originated from the name of the directory it lives in.<\/p>\n
So since our directory is named docker-hive, this explains the new network.<\/p>\n
Getting more information.<\/p>\n
Docker inspect can retrieve low-level information on Docker objects. You can pick out any field from the returned JSON.<\/p>\n
Let’s get the IP Address from the dockerhive_datanode.<\/p>\n
\n>docker ps --format "table {{.ID}}\\t{{.Status}}\\t{{.Names}}"\nCONTAINER ID STATUS NAMES\n30714f65fc36 Up 2 minutes docker-hive_hive-metastore_1\ncc281caa92ba Up 2 minutes docker-hive_hive-server_1\n66aed41cdc5e Up 2 minutes docker-hive_hive-metastore-postgresql_1\nd90c10f7cfe6 Up 2 minutes (healthy) docker-hive_datanode_1\nbaf998183015 Up 2 minutes (healthy) docker-hive_namenode_1\n<\/pre>\nGet the container ID from the above command to find the following:<\/p>\n
\n$ docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' d90c10f7cfe6\n172.20.0.2\n<\/pre>\nDocker Logs<\/p>\n
How to check Docker logs
\nsudo docker logs where is the ID of the docker container<\/p>\nGet Docker Container:<\/p>\n
\n# sudo docker ps --format "table {{.ID}}\\t{{.Status}}\\t{{.Names}}"\n<\/pre>\nNow view the logs:<\/p>\n
\n$ sudo docker logs d90c10f7cfe6 \n<\/pre>\nDocker Ports<\/p>\n
\n$ docker container ls --format "table {{.ID}}\\t{{.Names}}\\t{{.Ports}}" -a\nCONTAINER ID NAMES PORTS\na624f0ae744e cool_moore\na0d9f2b7ce84 zealous_mclean 0.0.0.0:80->80\/tcp, :::80->80\/tcp\n<\/pre>\ndocker inspect<\/p>\n
This method allows one to return low-level information on the container or image.
\nSyntax<\/p>\n
docker inspect Container\/Image <\/p>\n
Select IP <\/p>\n
\n# docker inspect c52b91aa0dea | grep -i ip\n<\/pre>\nPorts<\/p>\n
