Hi,
I am trying to establish ros connection between 2 dockers. Details given below.
1. Lets consider I have **docker_1** and **docker_2**.
2. I am able to publish message from **docker_1** and subscribe it to **docker_2** provided my ```roscore``` is running in **docker_1**.
3. When I try to publish message from **docker_2** and subscribe it from **docker_1** I am getting the below error.
```[ERROR] [WallTime: 1553869754.845807] Unable to connect subscriber to publisher [http://172.17.0.1:44027/] for topic [/check]: unable to requestTopic: [Errno 111] Connection refused```
IP details:
docker_1 :
ROS_MASTER_URI = http://172.17.0.1:11311
ROS_IP = 172.17.0.1
==========================================
docker_2 :
ROS_MASTER_URI = http://172.17.0.1:11311
ROS_IP = 172.17.0.1
Could you please help me to fix this.
Thank you,
KK
