Question

The CI Pipeline console gives an error: - Get https://registry-1.docker.io/v2: net / http: the request was canceled while waiting for the connection

I installed Concourse CI using a BOSH deployment on AWS .

After a successful installation, I can see Concourse CI in the browser. I created a hi-world conveyor using the official Course CI page: - http://concourse-ci.org/getting-started.html

But when I try to run the assembly for the hello-world pipeline, I get an error: -

Get https://registry-1.docker.io/v2: net/http: request canceled while waiting for connection

Please let me know how I can fix this problem. Thanks in advance. My CI Pipeline Code: -

jobs:        
- name: hello-world     
  plan:      
  - task: say-hello    
    config:   
      platform: linux   
      image: "docker:///ubuntu"   
      run:  
        path: echo  
        args: ["Hello, world!"]
