Getting Started with docker

Thanks for nice write up.. I was not able install successfully,looks something I missed..Below the snapshot for same.

and OzoneConfiguration and simple script  links are not working.

root@brahma:/home/brahma/trunk/hadoop/hadoop-ozone/dist/target/ozone-0.4.0-SNAPSHOT/compose/ozone# ozone freon randomkeys --numOfVolumes=10 --numOfBuckets 10 --numOfKeys 10 --replicationType=RATIS --factor=THREE
No command 'ozone' found, did you mean:
Command 'iozone' from package 'iozone3' (multiverse)
ozone: command not found
root@brahma:/home/brahma/trunk/hadoop/hadoop-ozone/dist/target/ozone-0.4.0-SNAPSHOT/compose/ozone# docker-compose ps
root@brahma:/home/brahma/trunk/hadoop/hadoop-ozone/dist/target/ozone-0.4.0-SNAPSHOT/compose/ozone#

OS:

Linux brahma 4.13.0-39-generic #44~16.04.1-Ubuntu SMP Thu Apr 5 16:43:10 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Can you run this command from inside datanode instance. That is after the

> docker-compose exec datanode bash

if you are inside the datanode, the ozone shell command will be in path.

Else, ozone command will in the bin directory of ozone, just like Hadoop.

You can execute the ozone command from that location too. Ozone is a shell wrapper just like hdfs command.

Also we have some prepackaged ozone docker images in the tree now; so you can do a

> mvn clean install -T 1C -Phdds -DskipTests=true -Dmaven.javadoc.skip=true -DskipShade

and then you can go to the dist directory to find all kinds of docker images, the most simple one  is

> /hadoop-ozone/dist/target/ozone-0.4.0-SNAPSHOT/compose/ozone

I still dn't have the luck.anything else I am missing, sorry to trouble you.

root@brahma:/home/brahma/trunk/hadoop/hadoop-ozone/dist/target/ozone-0.4.0-SNAPSHOT/compose/ozone# mvn clean install -T 1C -Phdds -DskipTests=true -Dmaven.javadoc.skip=true -DskipShade

So what is the output of 'docker-compose logs' command? Do you see any error there?

Looks problem docker-compose.. I re-installed..Now it's ok.. Thanks guys.
