Why my array suddenly lose all its content

I have read some posts that are related with my question but I'm a bit lost. What I'm trying to do is to add values of a collection in a Array and value of Docker in an other one. I can put the values in the 2 arrays but suddently the seconde one lose all his data.
There is my code:

triggerState = Meteor.bindEnvironment(function() {
  console.log("Start triggerState");

  //clean the 2 arrays
  stateLastCheck.length = 0;
  stateDockerLastCheck.length = 0;

  //add the collection value in the array
  InfosContainers.find().forEach(Meteor.bindEnvironment(function(ctn) {
    stateLastCheck.push(ctn.stateContainer);
    console.log("stateLastCheck " + stateLastCheck.length);
  }));
  console.log("end stateLastchek");

  //take the actual values
  docker.listContainers({
    all: true
  }, Meteor.bindEnvironment(function(err, containers) {
    containers.forEach(function(containerInfo) {
      stateDockerLastCheck.push(containerInfo.State);
      console.log("stateDockerLastCheck" + stateDockerLastCheck.length);
    });
  }));
  console.log("end stateDockerLastCheck");

  //compare last with actual
  for (var i = 0; i < stateLastCheck.length; i++) {
    console.log("Size of last and docker: " + stateLastCheck.length + " et " + stateDockerLastCheck.length);
    if (stateLastCheck[i].includes(stateDockerLastCheck[i])) {
      console.log("no problemos")
    } else {
      console.log("there is a changement of state:  " + stateLastCheck[i] + stateDockerLastCheck[i]);
      break;
    }
  }
  setTimeout(triggerState, 7000);
});

Then if I use my logs I can see that suddently the docker array is empty and that the loop is made again:

I think I should use some wait but I'm really lost so if someone could help me ?

After adding some '---' in my code I noticed that the input is really strange :
