EmqxContainer

Appears in:

Field Description Default Validation
image EmqxImage Container image.
The image is generated by "${Registry}/${Repository}:${Prefix}${Version}${Suffix}".
command string array Entrypoint array. Not executed within a shell.
The container image's ENTRYPOINT is used if this is not provided.
Variable references $(VAR_NAME) are expanded using the container's environment. If a variable
cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced
to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will
produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless
of whether the variable exists or not. Cannot be updated.
More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell
args string array Arguments to the entrypoint.
The container image's CMD is used if this is not provided.
Variable references $(VAR_NAME) are expanded using the container's environment. If a variable
cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced
to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will
produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless
of whether the variable exists or not. Cannot be updated.
More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell
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.
Cannot be updated.
ports ContainerPort array List of ports to expose from the container. Exposing a port here gives
the system additional information about the network connections a
container uses, but is primarily informational. Not specifying a port here
DOES NOT prevent that port from being exposed. Any port which is
listening on the default "0.0.0.0" address inside a container will be
accessible from the network.
Cannot be updated.
envFrom EnvFromSource array List of sources to populate environment variables in the container.
The keys defined within a source must be a C_IDENTIFIER. All invalid keys
will be reported as an event when the container is starting. When a key exists in multiple
sources, the value associated with the last source will take precedence.
Values defined by an Env with a duplicate key will take precedence.
Cannot be updated.
env EnvVar array List of environment variables to set in the container.
Cannot be updated.
resources ResourceRequirements Compute Resources required by this container.
Cannot be updated.
More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/
volumeMounts VolumeMount array Pod volumes to mount into the container's filesystem.
Cannot be updated.
volumeDevices VolumeDevice array volumeDevices is the list of block devices to be used by the container.
livenessProbe Probe Periodic probe of container liveness.
Container will be restarted if the probe fails.
Cannot be updated.
More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes
readinessProbe Probe Periodic probe of container service readiness.
Container will be removed from service endpoints if the probe fails.
Cannot be updated.
More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes
startupProbe Probe StartupProbe indicates that the Pod has successfully initialized.
If specified, no other probes are executed until this completes successfully.
If this probe fails, the Pod will be restarted, just as if the livenessProbe failed.
This can be used to provide different probe parameters at the beginning of a Pod's lifecycle,
when it might take a long time to load data or warm a cache, than during steady-state operation.
This cannot be updated.
More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes
lifecycle Lifecycle Actions that the management system should take in response to container lifecycle events.
Cannot be updated.
terminationMessagePath string Optional: Path at which the file to which the container's termination message
will be written is mounted into the container's filesystem.
Message written is intended to be brief final status, such as an assertion failure message.
Will be truncated by the node if greater than 4096 bytes. The total message length across
all containers will be limited to 12kb.
Defaults to /dev/termination-log.
Cannot be updated.
terminationMessagePolicy TerminationMessagePolicy Indicate how the termination message should be populated. File will use the contents of
terminationMessagePath to populate the container status message on both success and failure.
FallbackToLogsOnError will use the last chunk of container log output if the termination
message file is empty and the container exited with an error.
The log output is limited to 2048 bytes or 80 lines, whichever is smaller.
Defaults to File.
Cannot be updated.
securityContext SecurityContext SecurityContext defines the security options the container should be run with.
If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext.
More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/ 		{ runAsGroup:1000 runAsNonRoot:true runAsUser:1000 }
stdin boolean Whether this container should allocate a buffer for stdin in the container runtime. If this
is not set, reads from stdin in the container will always result in EOF.
Default is false.
stdinOnce boolean Whether the container runtime should close the stdin channel after it has been opened by
a single attach. When stdin is true the stdin stream will remain open across multiple attach
sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the
first client attaches to stdin, and then remains open and accepts data until the client disconnects,
at which time stdin is closed and remains closed until the container is restarted. If this
flag is false, a container processes that reads from stdin will never receive an EOF.
Default is false
tty boolean Whether this container should allocate a TTY for itself, also requires 'stdin' to be true.
Default is false.
emqxConfig object (keys:string, values:string)
emqxACL string array
bootstrapAPIKeys BootstrapAPIKey array EMQX bootstrap user
Cannot be updated.
