If you want to test the automation with Cisco ACI, you can use the following container.

docker pull zednetwork/aci-dev:latest

root@docker1:~/aci-dev# docker images zednetwork/aci-dev
REPOSITORY           TAG                 IMAGE ID            CREATED             SIZE
zednetwork/aci-dev   latest              b1c09a7c66f0        About an hour ago   1.31GB

I preinstalled Ansible 2.9.11, the ACI SDK (COBRA) in version 4.2(4) and ARYA.

You can run directly the container with the command:

docker run -it <Image ID> bash

or start it with docker-compose command :

docker-compose up -d 

Docker-compose file :

---
version: "3"

services:
  aci-dev:
    image: zednetwork/aci-dev:latest
    stdin_open: true

and connect to the container :

root@docker1:~/aci-dev# docker-compose ps
      Name          Command   State   Ports
-------------------------------------------
aci-dev_aci-dev_1   bash      Up

root@docker1:~/aci-dev# docker exec -it  aci-dev_aci-dev_1 bash
