Workspaces

Sizing

Gitpod schedules workspaces as Kubernetes pods. Each workspace pod requests a certain amount of memory which directly affects how many workspaces are scheduled on a single node. If you want to change the default sizing (~ 8GiB per workspace) you should

1. Merge the following into your values.custom.yaml:

   # workspaceSizing configures the resources available to each workspace. These settings directly impact how
   # desenly we pack workspaces on nodes where workspacesPerNode = memoryAvailable(node) / memoryRequest.
   #
   # Beware: if a workspace exceeds its memoryLimit, some of its processes may be terminated (OOM-kill) which
   # results in a broken user experience.
   workspaceSizing:
     requests:
       cpu: "1m"
       memory: "2.25Gi"
       storage: "5Gi"
     limits:
       cpu: "5"
       memory: "12Gi"
     dynamic:
       # Gitpod supports dynamic CPU limiting. We express those limits in "buckets of CPU time" (jiffies where 1 jiffie is 1% of a vCPU).
       # Each bucket has a limit (i.e. max CPU rate in jiffies/sec, 100 jiffies/sec = 1 vCPU).
       #
       # For example:
       #   # three minutes of 5 CPUs: 5 [numCPU] * 100 [jiffies/sec] * (3 * 60) [seconds] = 90000
       #   - budget: 90000
       #     limit: 500
       #   # five minutes  of 4 CPUs: 4 [numCPU] * 100 [jiffies/sec] * (5 * 60) [seconds] = 120000
       #   - budget: 120000
       #     limit: 400
       #   # remainder of 2 CPUs where a user has to stay below sustained use of 1.8 CPUs for 5 minutes:
       #   #                       1.8 [numCPU] * 100 [jiffies/sec] * (5 * 60) [seconds] = 54000
       #   - budget: 54000
       #     limit: 200
       #
       # if there are no buckets configured, the dynamic CPU limiting is disabled.
       cpu:
         buckets: []
         samplingPeriod: "10s"
         controlPeriod: "15m"

2. Do a helm upgrade --install -f values.custom.yaml gitpod gitpod.io/gitpod --version=0.9.0 to apply the changes.
