Default Profile

Dozzle persists per-user UI preferences (theme, locale, pinned containers, collapsed groups, visible JSON keys, etc.) to disk under /data/<username>/profile.json. When authentication is disabled, or for any user before they have signed in and customized their settings, Dozzle falls back to a special profile named __default__.

You can ship a pre-configured profile by creating the file /data/__default__/profile.json. Anonymous visitors and any new user without a saved profile will load these settings on first visit.

File Location

/data/__default__/profile.json

If the file does not exist, Dozzle starts with built-in defaults. You only need to create it if you want to override them.

Example

{
  "settings": {
    "showTimestamp": true,
    "showStd": false,
    "showAllContainers": false,
    "softWrap": true,
    "collapseNav": false,
    "smallerScrollbars": false,
    "search": false,
    "compact": false,
    "menuWidth": 15,
    "size": "medium",
    "lightTheme": "auto",
    "hourStyle": "auto",
    "dateLocale": "auto",
    "locale": "en",
    "groupContainers": "at-least-2",
    "automaticRedirect": "delayed"
  },
  "pinned": [],
  "visibleKeys": [],
  "collapsedGroups": []
}

All fields are optional — include only the ones you want to override.

Available Settings

Field	Type	Description
showTimestamp	boolean	Show timestamps next to each log line
showStd	boolean	Show stdout/stderr stream indicator
showAllContainers	boolean	Include stopped containers in the sidebar
softWrap	boolean	Wrap long log lines instead of horizontal scroll
collapseNav	boolean	Start with the sidebar collapsed
smallerScrollbars	boolean	Use thinner scrollbars
search	boolean	Enable inline search by default
compact	boolean	Compact log row spacing
menuWidth	number	Sidebar width as a percentage of the window. Capped at 50.
size	string	Font size: small, medium, large
lightTheme	string	Theme preference: auto, light, dark
hourStyle	string	Time format: auto, 12, 24
dateLocale	string	Date/time formatting: auto, en-US, en-GB, de-DE, en-CA
locale	string	UI language (e.g. en, fr, de)
groupContainers	string	Sidebar grouping: always, at-least-2, never
automaticRedirect	string	Redirect to a new container: instant, delayed, none

Values outside these sets are not accepted, so groupContainers: "stack" or a dateLocale of fr-FR will not do what you expect.

The top-level fields pinned, visibleKeys, and collapsedGroups accept arrays and let you pre-pin containers or pre-collapse groups for first-time visitors. Dozzle also writes releaseSeen, dismissedImageUpdates, and dismissedLinkHint at the top level to remember what a user has already dismissed. Seeding dismissedLinkHint: true suppresses the first-run link hint for everyone.

How It Works

• On page load, Dozzle reads /data/<username>/profile.json for the signed-in user, or /data/__default__/profile.json when no user is authenticated.
• When a user changes a setting in the UI, the new value is persisted under their own username (or back into __default__ when auth is disabled).
• The __default__ profile is therefore both the template for new visitors and the live profile for the anonymous user in unauthenticated deployments.

TIP

If you only want to seed defaults but still let the anonymous user customize them at runtime, mount the file read-only — Dozzle will fail to persist changes but the UI continues to work.
