"ERROR: Get "https://gcr.io/v2/": x509: certificate signed by unknown authority" In docker for windows OS

Question

I am trying to setup an application which is having python and graph QL as backend and is using radis, while building nginx using

'
 docker-compose --profile backend --profile frontend  up --build
'

it is pulling radis and then getting failed with

ERROR- Get "https://gcr.io/v2/": x509: certificate signed by unknown authority.

I am using it on windows ,

I tried by two ways-

1 Placing file in "Programdata\Docker\config\daemon.json" which is having below content,

'
{
"insecure-registries" : [ "your.registry.host:5000" ]
}
'

2. Adding content in C:\Program Files\Docker\Docker\resources\windows-daemon-options.json

   '
   { "insecure-registries": [ "your.registry.host:5000" ] } '

But no luck, Any help is appreciated

As an alternate solution update your docker-compose.yml script with google/<docker_name> instead of gcr.io

For example:

cadvisor:
    image: gcr.io/cadvisor/cadvisor:latest

To

cadvisor:
    image: google/cadvisor:latest
