While trying to build a service on docker-machine i got an error of "image doesn't exist" on that docker-machine manager node. As I checked the docker images command on the manager node, no image was there as expected. But on the root docker side I have those images. I want to access these images on the manager node. I've read few articles where it was mentioned that, maybe I've to upload that image on the docker hub then pull it from that hub. But I want to access it locally. Is there any way to do this as I'm newbie to docker.
This is the command what I tried on my manager machine:
docker@manager:~$ docker service create --name "api-client" -p 4200:4200 api_client
This is my docker images output:
REPOSITORY TAG IMAGE ID CREATED SIZE
api_client latest 097b19c4deb8 27 hours ago 1.15GB
But on my docker@manager terminal, my docker image folder is empty.
The problem is that there is no repository to hold the image. The repository needs to be pulled from to a repository to each node in the Swarm before it can execute. In general you need to do the following:
Setup a repository, if you want a local repository there is a guide here, but it will be some hassle to get it up and running i and "insecure http" version. An easier way is to get yourself a free docker hub account and put your image there.
Tag your local image with the repository name. Howto is shown in the guide above.
docker tag <local image> <repository>/<image:tag>
docker login
docker push <repository>/<image>:<tag>
docker service create --name "api-client" -p 4200:4200 <repository>/<image>:<tag>
Your can also try to pull an image into the local cache of a node using
docker pull <repository>/<image>:<tag>
