Detailed installation and use of RocketMQ in Docker

To search for RocketMQ images, you can search on Docker's hub.docker.com, or you can search through Docker's search command in Linux. However, after the recent firewall upgrade, foreign websites are opened very slowly. It is more convenient to search through commands. To operate Docker commands, you must be the root user or a user with root privileges. The query operation is as follows:

docker search rocketmq

The following results can be obtained:

There are quite a lot of images, but none of them are officially released. I will just pick one, such as foxiswho/rocketmq. The following is a shell command to view all versions of the current image:

curl https://registry.hub.docker.com/v1/repositories/foxiswho/rocketmq/tags\
| tr -d '[\[\]" ]' | tr '}' '\n'\
| awk -F: -v image='foxiswho/rocketmq' '{if(NR!=NF && $3 != ""){printf("%s:%s\n",image,$3)}}'

If you want to view other images, just replace the image name foxiswho/rocketmq with other images. Execute the command to get the following results:

The following is to start the nameserver and broker step by step.

Start the NameServer:

docker run -d -p 9876:9876 --name rmqserver foxiswho/rocketmq:server-4.5.1

Start the broker:

docker run -d -p 10911:10911 -p 10909:10909\
 --name rmqbroker --link rmqserver:namesrv\
 -e "NAMESRV_ADDR=namesrv:9876" -e "JAVA_OPTS=-Duser.home=/opt"\
 -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m"\
 foxiswho/rocketmq:broker-4.5.1

The default configuration file path in the Broker container is:

/etc/rocketmq/broker.conf

You can also specify the local configuration file through the -v parameter:

docker run -d -p 10911:10911 -p 10909:10909\
 --name rmqbroker --link rmqserver:namesrv\
 -e "NAMESRV_ADDR=namesrv:9876" -e "JAVA_OPTS=-Duser.home=/opt"\
 -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m"\
 -v /conf/broker.conf:/etc/rocketmq/broker.conf \
 foxiswho/rocketmq:broker-4.5.1

If everything goes well, NameServer and Broker will be installed in a short while. For the convenience of management, rocketmq console is also an indispensable tool. Find the version to be started through the above query method. The startup method is as follows:

docker run -d --name rmqconsole -p 8180:8080 --link rmqserver:namesrv\
 -e "JAVA_OPTS=-Drocketmq.namesrv.addr=namesrv:9876\
 -Dcom.rocketmq.sendMessageWithVIPChannel=false"\
 -t styletang/rocketmq-console-ng

Then check the startup status with the following command:

docker ps | grep rocketmq

The results are as follows:

Then access localhost:8180 through the browser, the console page is displayed as follows:
