odo deploy
odo can be used to deploy components in a similar manner they would be deployed by a CI/CD system,
by first building the images of the containers to deploy, then by deploying the Kubernetes resources
necessary to deploy the components.
When running the command odo deploy, odo searches for the default command of kind deploy in the devfile, and executes this command.
The kind deploy is supported by the devfile format starting from version 2.2.0.
The deploy command is typically a composite command, composed of several apply and exec commands:
an
applycommand referencing animagecomponent that, when applied, will build the image of the container to deploy, and push it to its registry,an
applycommand referencing akubernetescomponent that, when applied, will create a Kubernetes resource in the cluster.an
execcommand referencing a container component that, when applied, will run the command defined bycommandLineinside a container started by a Kubernetes Job; read more about it here.With the following example
devfile.yamlfile, a container image will be built by using theDockerfilepresent in the directory, the image will be pushed to its registry and a Kubernetes Deployment will be created in the cluster, using this freshly built image.

The uri for the Dockerfile could also be an HTTP or HTTPS URL.
It may also point to a Containerfile.
Depending upon the container registry specified in the devfile.yaml, the access for container image
pushed by odo deploy may be private by default. For example: images pushed to Quay.io. Change the
image visibility appropriately in order to run odo deploy successfully.

Passing extra args to Podman or Docker when building images
Similarly to how odo build-images works, you can set the ODO_IMAGE_BUILD_ARGS environment variable,
which is a semicolon-separated list of extra arguments to pass to Podman or Docker when building images.
See this section for further details.
ODO_IMAGE_BUILD_ARGS='arg1=value1;arg2=value2;...;argN=valueN' odo deploy
Example
$ ODO_IMAGE_BUILD_ARGS='--platform=linux/amd64;--build-arg=MY_ARG=my_value' odo deploy
__
/ \__ Running the application in Deploy mode using my-nodejs-app Devfile
\__/ \ Namespace: default
/ \__/ odo version: v3.10.0
\__/
⚠ You are using "default" namespace, odo may not work as expected in the default namespace.
⚠ You may set a new namespace by running `odo create namespace <name>`, or set an existing one by running `odo set namespace <name>`

Substituting variables
The Devfile can define variables to make the Devfile parameterizable. The Devfile can define values for these variables, and you
can override the values for variables from the command line when running odo deploy, using the --var and --var-file options.
See Substituting variables in odo dev for more information.
