Scaling jobs

With dokkup's scaling feature, you can easily change the number of running containers on your nodes.

Note

Upscaling or downscaling a job will not have an effect on your uptime.

Upscale a job

If you want to increase the number of running containers, you can do so by incrasing the count field in your job specification, then run the dokkup run job command:

demo.yaml
group: "labs"
# count: 2
count: 5
name: "demo"

container:
 - image: "crccheck/hello-world"
   ports:
    - in: 8000
   restart: always 
   labels:
     - "my.label.test=demo"
   environment:
     - MYENV=ENVEXAMPLE
   volumes:
     - myvolume:/home

$ dokkup run job demo.yaml

Deployment summary:

NAME     IMAGE                    RESTART     COUNT     GROUP     NETWORK
test     crccheck/hello-world     always      5         local     bridge

Node statuses:

NAME          STATUS     CONTAINERS     UPDATE     VERSION
lab1          ONLINE     2 -> 5         true       55dab32
lab2          ONLINE     2 -> 5         true       55dab32

Downscale a job

If you want to decrease the number of running containers, you can do so by decreasing the count field in your job specification, then run the dokkup run job command:

demo.yaml
group: "labs"
# count: 5
count: 2
name: "demo"

container:
 - image: "crccheck/hello-world"
   ports:
    - in: 8000
   restart: always 
   labels:
     - "my.label.test=demo"
   environment:
     - MYENV=ENVEXAMPLE
   volumes:
     - myvolume:/home

$ dokkup run job demo.yaml

Deployment summary:

NAME     IMAGE                    RESTART     COUNT     GROUP     NETWORK
test     crccheck/hello-world     always      2         local     bridge

Node statuses:

NAME          STATUS     CONTAINERS     UPDATE     VERSION
lab1          ONLINE     5 -> 2         true       55dab32
lab2          ONLINE     5 -> 2         true       55dab32
