Create Docker Image from .tar file
$ docker load --input my-dockerized-app-0.0.1.tar
Create a tag.
Before tag creating, i will learn my source image/newly created docker image ID for the tag creating command..
$ docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]
we can find that via “docker image ls”, but put the grep command, because i want only the same name having images seen, what I as grep argument given.
$ docker image ls | grep my-docker my-dockerized-app 0.0.1 c0f32faf4320 1 minute ago
And now i can create a new tag for local or for private docker registry
Option 1. Tag for Only Local Using
$ docker tag c0f32faf4320 my-dockerized-app:0.0.1
Option 2. Tag for Local and over Local/Open Registry
$ docker tag c0f32faf4320 docker.d8devs.com/apps/my-dockerized-app:0.0.1 $ docker push docker.d8devs.com/apps/my-dockerized-app:0.0.1
Example Usage:
in docker-compose.yml
version: '3' services: frontend: image: my-dockerized-app:0.0.1 ...... ..... ....
for Kubernetes deployment
apiVersion: apps/v1 kind: Deployment metadata: name: app-deployment labels: app: app-test spec: replicas: 1 selector: matchLabels: app: app-test template: metadata: labels: app: app-test spec: containers: - name: frontend image: my-dockerized-app:0.0.1 // or docker.d8devs.com/apps/my-dockerized-app:0.0.1 (dont forget use the imagePullSecrets for privat Registry)
