The Containers view grows up: choose your columns, see a web UI's bookmark and its health, get told when a container runs hot, let updates run at night with a rollback, and measure what Unraid's appdata takes. It leads the What's new window.

Containers

• new — automatic updates. A switch in a container's Updates section, or Update automatically in the selection bar, lets nextDash update it in a nightly window (Config → Containers → Updates, 03:00–05:00 at first). One container at a time, only what the last check found, never a skipped or held version or nextDash's own. Each update is watched for five minutes; a container that stops, restarts on its own or turns unhealthy is rolled back and the version skipped. Updates, rollbacks and failures send a notice. New docker_auto_update.go.
• new — a web UI's bookmark. A bookmark mark follows a container's web UI link in the colour of the bookmark's checks; a click opens the bookmark in the Bookmarks view, its row in view and in focus, on Details. It is found by hand (the side panel's new Bookmark section), else by the same port on this server, a subdomain named after the container, or its title — and not guessed between two. The bookmark's Details say Runs in back. Chosen links are kept in dockerBookmarkLinks.
• new — notices when a container runs hot. Above 90 % CPU of every core or 90 % memory of its limit for 10 minutes (each adjustable in Config → Containers → Notifications), and when it is back under. Reads the stats history. New docker_usage_alerts.go.
• new — Columns. Show or hide Image, Status, CPU, RAM, Size, Restarts, Web UI and Ports; remembered with the view. Restarts (off at first) counts starts again in the last 24 hours, from the timeline.
• new — sort by size and restarts, from the headings and the sort menu.
• new — group by network or by image, beside project and status.
• new — network and disk I/O in Resources: in/out and read/written now, and two more charts of the last hour.
• new — Disk: remove stopped containers in one go, after naming them; volumes and images stay, hidden ones and nextDash's own are left.
• new — Disk: measure a bind mount's folder. A short-lived alpine container mounts it read-only with no network and runs du; only folders a container mounts can be measured. New POST /api/docker/binds/measure.
• new — an ℹ in the header explains the view, as Bookmarks and Inbox have.
• fix — a followed container log stayed silent in the browser. The gzip middleware asserted http.Flusher on the request log's recorder, which only has Unwrap, so nothing was flushed until 4 KB had piled up. It now flushes through http.ResponseController.
• fix — the side panel's Volumes and Health were hard to read. A mount shows where it appears in the container, with where it comes from under it and tags for its kind and read-only; the health check sits in its own block, and each last check is a mark and a time in one column.

Bookmarks

• fix — a bookmark further down than the first page lost its cursor when opened from elsewhere; the list is drawn down to it and scrolled to it.
• fix — after closing the side panel with the mouse, the page would not scroll until Escape: the row stayed the cursor and kept Space and the arrow keys. Closed with the mouse it lets go; closed with Escape or i it stays.

What's new

• fix — Support and Esc sit in the header's right corner.

Tests

• fix — the update-status fixture let a test end mid-fetch without failing it.

Docs

• docs — MANUAL §11.3 and §14, Config → Help and four new tips describe all of the above, in six languages; README's Containers caption too. static/data/whats-new/v1.15.6.json, its index entry and two Overview entries (the bookmark link and automatic updates); whats-new-stub.js moves DASHBOARD_RELEASE to v1.15.6 and NEXTDASH_WHATS_NEW_DATA_VERSION to whats-new-v310.
