Table 3‑7. Health Conﬁguration Modes

Mode Description

None Default. No health checks are configured.

HTTP If you select HTTP, you must provide an API to access and

an HTTP method and version to use . The API is relative and

you do not need to enter the address of the container. You

can also specify a timeout period for the operation and set

health thresholds.

For example, a healthy threshold of 2 means that two

consecutive successful calls must occur for the container to

be considered healthy and in the RUNNING status. An

unhealthy threshold of 2 means that two unsuccessful calls

must occur for the container to be considered unhealthy and

in the ERROR status. For all the states in between the

healthy and unhealthy thresholds, the container status is

DEGRADED.

TCP connection If you select TCP connection, you must only enter a port for

the container. The health check attempts to establish a TCP

connection with the container on the provided port. You can

also specify a timeout value for the operation and set healthy

or unhealthy thresholds as with HTTP.

Command If you select Command, you must enter a command to be

executed on the container. The success of the health check is

determined by the exit status of the command.

Conﬁgure Links in Containers

Links and exposed services address communication across container services and load balancing across

hosts. You can configure link settings for your containers in Containers.

You can use links to enable communication between multiple services in your application. Links in

Containers are similar to Docker links, but connect containers across hosts. A link consists of two parts: a

service name and an alias. The service name is the name of the service or template being called. The

alias is the host name that you use to communicate with that service.
