Making request jq to output memory and container

Question

how to make request to output coantainer name and how much memory and cpu usage.

\"container\":{\"memory\":{\"request\":{\"bytes\":6.142515354e+08}},\"name\":\"testcontainer\",\"cpu\":{\"request\":{\"cores\":0.3}}

Answer 1

Your sample input is a bit of a mess. If you really have to deal with something like that, the best would be to modify the beginning and end of the string, to make it parseable as a JSON string:

"{ \"container\":{\"memory\":{\"request\":{\"bytes\":6.142515354e+08}},\"name\":\"testcontainer\",\"cpu\":{\"request\":{\"cores\":0.3}}}}"

Then you can run jq on it, e.g.:

< kubernetes.txt jq fromjson

yields:

{
  "container": {
    "memory": {
      "request": {
        "bytes": 614251535.4
      }
    },
    "name": "testcontainer",
    "cpu": {
      "request": {
        "cores": 0.3
      }
    }
  }
}

Now it's easy to write the queries to get the details you want, e.g.

< kubernetes.txt jq fromjson.container.memory.request
