Service¶
Attributes describing a MICO Service are mainly taken from Pivio.

| version* | Semantic version version number, commit hash or revision | 1.0.2, 1.2.0a, d99ada433bb1d69571... |
| vcsroot | Url to vcs root (e.g. GitHub link with branch) | https://github.com/UST-MICO/mico |
| dockerfile | Path to dockerfile relative to vcsroot | mico-core/Dockerfile |

DependsOn¶
DependsOn is an edge between two services. A service depends on another service. Additionally, it provides the attribute version. This attribute allows to implement an auto-update feature. It contains a version string in the semantic version format. This allows to determine the most recent compatible service.
Service Interface¶
| Attribute | Description | Example |
|---|---|---|
| serviceInterfaceName* | Unique short name suffix for shortName of service. |
rest |
| description* | Human readable description | This is a service interface |
| port* | This is a port number or a variable name | 1024 |
| protocol* | The name of the protocol which is supported by this interface | gRPC, SQL, CYPHER |
| transport_protocol* | This protocol is used to transport the previous protocol | http, mqtt |
| public_dns* | To be defined |
Application¶
Because an application is a service itself it also includes all attributes of a service even when not explicitly stated in the table.
| Attribute | Description | Example |
|---|---|---|
| ID* | UUID (Unique for every version) | 7e7e1828-e845-11e8-9f32-f2801f1b9fd1 |
