Install rabbitmq via docker in OS-X

How to install docker in OS-X

• I have installed docker in my OS-X machine using boot2docker VM
• Following is a detailed article that I have written regarding how docker works with boot2docer - Docker in OSX

Install rabbitmq

Search for rabbitmq

docker search rabbitmq

• Following is the available images for rabbitmq

Pull rabbitmq image

docker pull rabbitmq:latest

• This command will pull latest rabbitmq docker image to your computer

• Things to notice

  1. rabbitmq image name
  2. latest tag of the image(latest image)

• If you download rabbitmq from your own registry(private registry), you have to specifies the registry details with docker pull command

docker pull 10.2.4.201/rabbitmq:latest

• Things to notice

  1. 10.2.4.201 defines private registry host
  2. rabbitmq:latest defines rabbitmq image name and tag in the registry

• Now following are my available docker images

• More info on private docker registries - private-registry

Create a container from pulled image

docker run -d -p 5672:5672 -p 15672:15672  --name rabbitmq 10.2.4.201/rabbitmq

• Things to notice

  1. -p 5672:5672 -p 15672:15672 defines port forwarding
  2. --name rabbitmq defines name of the container
  3. -d allows to run container as a demon
  4. 10.2.4.201/rabbitmq defines image name

• Above command will creates a new docker container with name rabbitmq which can runs as a demon

Run rabbitmq

## start boot2docker
boot2docker up

## start rabbitmq container
docker start rabbitmq

• Now you can access rabbitmq via <boot2docker-ip>/15672

• In my scenario http://192.168.59.103:15672/

Access rabbitmq from localhost

• In above scenario we have to access rabbitmq via boot2docker ip, since docker installed in boot2docker vm

• In order to access rabbitmq via localhost, you have to define port-forwarding rules with VBoxManage (since I have installed boot2docker VM via oracle virtual box)

## first need to down boot2docker
boot2docker down

## define port forwarding rule for port 15672
VBoxManage modifyvm "boot2docker-vm" --natpf1 "rabbitmq-port-15672,tcp,127.0.0.1,15672,,15672"

## define port forwarding rule for port 5672
VBoxManage modifyvm "boot2docker-vm" --natpf1 "rabbitmq-port-5672,tcp,127.0.0.1,5672,,5672"

## up boot2docker 
boot2docker up

## start rabbitmq 
docker start rabbitmq

• Now you can access rabbitmq via localhost http://localhost:15672/

Rabbimq configuration

• When doing rabbitmq configurations you have to connect to rabbitmq container
• Following command allows you to access /bin/bash on running container

docker exec -i -t rabbitmq bash

• Things to notice

  1. exec execute command
  2. rabbitmq container name
  3. bash execute bash

• Now you are inside the rabbitmq container

• You can edit the rabbitmq configuration files to add more configurations
• Following are some rabbitmq config files

/etc/rabbitmq/rabbitmq.config
/etc/rabbitmq/enabled_plugins

• More on rabbitmq configurations - configurations

Rabbimq log files

• Log files are locatest in /var/log/rabbitmq
• Following are some rabbitmq log files

/var/log/rabbitmq/rabbit\@f8e92f15b87d.log
/var/log/rabbitmq/rabbit@f8e92f15b87d-sasl.log
