How can I use variables in json file?

There is a value that is used several times in a json file.

I want to make this value as a variable, and want the variable to be used instead of inserting string each time.

  "DOCKER_IMAGE": "registry.somewhere.com:tag",
  "components":[
    {
      "name": "component_1",
      "docker_image": $DOCKER_IMAGE
      ...
    },
    {
      "name": "component_2",
      "docker_image": $DOCKER_IMAGE
      ...
    }

Something like this.

How can I achieve this?

Short answer, you cannot do this in regular JSON. A possible workaround is to put placeholder text where you want the "variable" to be filled in, then globally replace it before decoding the JSON string.
