[docker/cli] Docker stack: no suitable node (scheduling constraints not satisfied on 14 nodes; host-m…

### ROOT CAUSE The issue arises because the Docker scheduler cannot find any nodes that meet the specified placement constraints. The services `edge-de1` and `edge-nl1` require nodes with labels `location == de1` and `location == nl1`, respectively. However, none of the 14 available nodes have these labels, leading to the scheduling failure. ### CODE FIX 1. **Verify Node Labels**: Ensure that the nodes in your cluster have the correct `location` labels (`de1` and `nl1`). You can check node labels using:

bash
   docker node ls --detail
   


2. **Update Constraints or Node Labels**: 
   - If nodes exist with `de1` or `nl1`, adjust the service constraints to match existing labels.
   - If labels are incorrect, correct them on the nodes.

3. **Adjust Service Configuration**:
   - Modify the `placement` constraints in `docker-compose.yml` to use existing node labels or remove constraints if they're not needed.

Here's the corrected `docker-compose.yml` without constraints:

yaml
services:
  edge-de1:
    image: test-private/test:1.1.3
    ports:
      - target: 80
        published: 9090
        mode: host
    deploy:
      mode: replicated
      replicas: 1
    environment:

      NODE_KEY: "123123123123123123123"
      TEST: V1
    configs:
      - source: test_index_v1
        target: /usr/share/nginx/html/index.html
      - source: base_config_v1
        target: /etc/xxxx/config.yml

  edge-nl1:
    image: test-private/test:1.1.3
    ports:
      - target: 80
        published: 9090
        mode: host
    deploy:
      mode: replicated
      replicas: 1
    environment:
      NODE_ID: 1234
      NODE_KEY: "1234123412341234123412341234"
      TEST: V1
    configs:
      - source: test_index_v1
        target: /usr/share/nginx/html/index.html
      - source: base_config_v1
        target: /etc/xxxx/config.yml


**Note**: Remove or adjust the `placement` constraints based on your node labels.
