Install Docker

API Developer

The API Connect Toolkit comes packaged with a Docker version of the API Gateway (DataPower) for testing full-featured policies locally on your workstation.

In order for you to be able to run the local API Gateway, you need to install Docker and make sure it's running.

Follow the instructions on the Docker website for your operating system to install the latest Docker Community Edition.

https://docs.docker.com/engine/installation/
Run the following command in a terminal window to verify that Docker is running:
```
docker ps
```
Troubleshooting:
The above command will list any running containers. It’s okay if the command shows no containers running at this time, as long as you do not see an error.

If you receive an error stating that there was no response from the Docker engine, follow these instructions to Configure and troubleshoot the Docker daemon
Make sure you have at least 4 GB of RAM that is available for Docker Containers, otherwise the Datapower Gateway container running locally will not start. Follow the documentation for your respective host OS running docker for more information.
