Service is an application deployed in D2C.
D2C executes your services/applications inside containers. We use Docker as our containerization platform. Each app is a separate container: web-app, database, load-balancer, etc. Docker is installed and configured on the hosts that are managed by D2C automatically. When you deploy your service, all the necessary files are delivered to the host, and container images are built locally on the host and then run by Docker daemon. D2C configures the environment automatically, so we do not recommend to add your current development boxes as managed hosts, to prevent any configuration conflicts.
Once you can deploy up to 50 containers (except services, which have their limitations).
Each service has its unique name. Services can communicate with each other by service names (or alias-names, e.g.
servicename). It doesn’t matter on which host the app is running – all private network intercommunication is transparent for services. Moreover, we use them to create public domains like: servicename-www.accountID.at.d2c.io for your services which are served by NGINX or HAProxy.
The name should starts with a letter and contain maximum 16 characters (initial, capital Latin symbols or numbers).

Actions which have all services:
- Update version
- Stop (Start)
- Destroy (+force destroy)
- Edit settings
- Scale (except some services e.g. NGINX)
- Add load-balancer
- Execute - executing a command inside all running service containers
All application services have smart update feature which you can choose separately or combine with each other:
- Update version (data and other services have only this one)
- Update global dependencies
- Update local dependencies
- Update sources
- Include .git folder
Interacting with service¶
Each service has system logs (deploy logs).
The line which has ellipsis marks, in the end, can be opened with a mouse click.
Messages of building images consist stdout, and it also can be shown.
