Container

A single application container. This specifies both the container to run, the command to run in the container and the arguments to supply to it. Note that additional arguments can be supplied by the system to the container at runtime.

Fields
name

string

Name of the container specified as a DNS_LABEL (RFC 1123).
image

string

Required. Name of the container image in Dockerhub, Google Artifact Registry, or Google Container Registry. If the host is not provided, Dockerhub is assumed.
command[]

env[]

object (EnvVar)

List of environment variables to set in the container.
resources

object (ResourceRequirements)

Compute Resource requirements by this container.
ports[]

object (ContainerPort)

List of ports to expose from the container. Only a single port can be specified. The specified ports must be listening on all interfaces (0.0.0.0) within the container to be accessible.

If omitted, a port number will be chosen and passed to the container through the PORT environment variable for the container to listen on.
volumeMounts[]

object (VolumeMount)

Volume to mount into the container's filesystem.
workingDir

string

Container's working directory. If not specified, the container runtime's default will be used, which might be configured in the container image.
livenessProbe

object (Probe)

Periodic probe of container liveness. Container will be restarted if the probe fails.
startupProbe

object (Probe)

Startup probe of application within the container. All other probes are disabled if a startup probe is provided, until it succeeds. Container will not be added to service endpoints if the probe fails.
dependsOn[]

string

Names of the containers that must start before this container.

EnvVar

EnvVar represents an environment variable present in a Container.

JSON representation 
{
  "name": string,

  // Union field values can be only one of the following:

  // End of list of possible types for union field values.
}
Fields
name

string

Required. Name of the environment variable. Must not exceed 32768 characters.

Union field values.

values can be only one of the following:
value

string

Variable references $(VAR_NAME) are expanded using the previous defined environment variables in the container and any route environment variables. If a variable cannot be resolved, the reference in the input string will be unchanged. The $(VAR_NAME) syntax can be escaped with a double $$, ie: $$(VAR_NAME). Escaped references will never be expanded, regardless of whether the variable exists or not. Defaults to "", and the maximum length is 32768 bytes.
valueSource

object (EnvVarSource)

Source for the environment variable's value.

EnvVarSource

EnvVarSource represents a source for the value of an EnvVar.

JSON representation

Fields
secretKeyRef

object (SecretKeySelector)

Selects a secret and a specific version from Cloud Secret Manager.

SecretKeySelector

SecretEnvVarSource represents a source for the value of an EnvVar.

JSON representation 
{
  "secret": string,
  "version": string
}
Fields
secret

string

Required. The name of the secret in Cloud Secret Manager. Format: {secretName} if the secret is in the same project. projects/{project}/secrets/{secretName} if the secret is in a different project.

The Cloud Secret Manager secret version. Can be 'latest' for the latest version, an integer for a specific version, or a version alias.

ResourceRequirements

ResourceRequirements describes the compute resource requirements.

JSON representation 
{
  "limits": {
    string: string,
    ...
  },
  "cpuIdle": boolean,
  "startupCpuBoost": boolean
}
Fields
limits

map (key: string, value: string)

Only memory and cpu keys in the map are supported.

Notes: * The only supported values for CPU are '1', '2', '4', and '8'. Setting 4 CPU requires at least 2Gi of memory. For more information, go to https://cloud.google.com/run/docs/configuring/cpu. * For supported 'memory' values and syntax, go to https://cloud.google.com/run/docs/configuring/memory-limits

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
cpuIdle

boolean

Determines whether CPU is only allocated during requests (true by default). However, if ResourceRequirements is set, the caller must explicitly set this field to true to preserve the default behavior.
startupCpuBoost

boolean

Determines whether CPU should be boosted on startup of a new container instance above the requested CPU threshold, this can help reduce cold-start latency.

ContainerPort

ContainerPort represents a network port in a single container.

JSON representation 
{
  "name": string,
  "containerPort": integer
}
Fields
name

string

If specified, used to specify which protocol to use. Allowed values are "http1" and "h2c".
containerPort

integer

Port number the container listens on. This must be a valid TCP port number, 0 < containerPort < 65536.

Fields
name

string

Required. This must match the Name of a Volume.
