Hi Folks
Just wanted to know… I have created django application Image by using DockerFile just wanted to know “How to Run Locally Built Docker Images in Kubernetes kind cluster using docker-compose file” ?
could you please help me out?

#2

Al West:
So Kubernetes does not use docker-compose files. To run your Django app you can either use the command line (imperative):

kubectl run django --image django

or supply a yaml file (declarative):

apiVersion: v1
kind: Pod
metadata:
  creationTimestamp: null
  labels:
    run: django
  name: django
spec:
  containers:
  - image: django
    name: django

and then save it as django.yaml and apply it with:

kubectl apply -f django.yaml

Nakul Desai:
@Al West thank you…but just wanted to know like if I wanted to use locally created image in pod how to achieve this?

#4

Al West:
you’d have to add the image to a registry to use it

#5

Nakul Desai:
@Al West I have Ubuntu also while trying to execute “docker login” command in CLI I am not able to log into docker registery. I am getting below error

“Error saving credentials: error storing credentials - err: exec: “docker-credential-desktop”: executable file not found in $PATH, out: ``”

#6

Al West:
how did you install docker? With snap?

#7

Nakul Desai:
Installed docker using command

apt install <http://docker.io|docker.io> -y
#8

Al West:
I never use the distribution version of Docker, as it is usually out of date. I would install direct from docker:
https://docs.docker.com/engine/install/ubuntu/
Or you can try to edit ~/.docker/config.json and add ths:

{
     "credsStore": "pass"
}
#9

Nakul Desai:
ohkk…got it I will try this one and will get back to you…thanks :innocent:

#10

Nakul Desai:
In ~/.docker/config.json I have

{
     "credsStore": "desktop"
}
#11

Al West:
change it to pass

#12

Nakul Desai:
yes I have tried but giving the same error

#13

Al West:
did you restart docker?

#14

Nakul Desai:
yes tried giving this same kind of error

“Error saving credentials: error storing credentials - err: exec: “docker-credential-pass”: executable file not found in $PATH, out: ``”

#15

Al West:
Move the config.json file out of the .docker directory and restart docker

#16

Nakul Desai:
yaa…this one work thanks :innocent:so should I put config.json file again into .docker/ again or its ok to place outside of that dir.

#17

Al West:
just leave it out as it seems to be interfering with the credentials manager

#18

Nakul Desai:
ok sure… just let me help in the flow…so now I can push locally created image into registry and will create Docker-compose file to pull that image to create container is this right?

#19

Nakul Desai:
Also just wanted to know the reason behind the getting error for config.json file?

#20

Al West:
Credentials setting was incorrect. Again, I wouldn’t install Docker using distribution package and would only get Docker direct from the Docker project.
