This presentation introduces the FIWARE Docker Container Service (FDCS) and describes how you can start using the service. FDCS allows you to manage your docker containers, volumes, and networks remotely from your local Docker client. You do not have to worry about creating or managing docker hosts, since the service maintains a cluster of docker hosts that you can use. Many tenants may share the service’s resources, but they are isolated from each other.

4. Getting started is simple
1. Sign up FIWARE lab account (https://account.lab.fiware.org/sign_up/)
2. Apply for access to the service
– Contact nagin@il.ibm.com
3. Setup your local environment to work remotely with the service.
4. Use docker!
– Both Docker CLI and Docker Compose can be used out of the box

5. 7
Set up your local environment
remote docker host endpoint
DOCKER_HOST:
>export
DOCKER_HOST=tcp://docker.lab.fiware.org:2376
>docker <cmd>
docker –H flag:
>docker -H tcp://docker.lab.fiware.org:2376 <cmd>
>docker [--config <config.json directory>] <cmd>

6. 8
Set up your local environment
config.json
config.json:
{ "HttpHeaders":
{
"X-Auth-Token": <keystone token>,
"X-Auth-TenantId": <keystone tenant id>
}
}
config.json describes additional headers to send to a remote docker service.
By default in $HOME/.docker/config.json, but docker –config can override default.
>docker <cmd>
>docker [--config <config.json directory>] <cmd>

7. 9
Set up your local environment
set_docker_conf.bash
>export TENANT_NAME=<user’s organization, e.g. ‘username cloud'
>export USERNAME=<user’s email address, e.g. ‘username@gmail.com’
>export PASSWORD=<user’s password>
>export KEYSTONE='http://cloud.lab.fi-ware.org:4730/v2.0/'
>set_docker_config.bash
set_docker_conf.bash updates config.json with your keystone token and tenant id.
