Dockerfile fails with Deno 2.x - "deno install -A" no longer works

[GuideThomas]

Problem

The current Dockerfile fails to build with Deno 2.x (tested with 2.3.1):

error: the following required arguments were not provided:
  --global

Note: Permission flags can only be used in a global setting

Cause

Deno 2.x changed the syntax for deno install. The -A flag (allow all permissions) is no longer valid for local installs.

Solution

Update the Dockerfile to use --allow-import instead:

FROM denoland/deno:2.3.1
WORKDIR /app
COPY . .
RUN deno install --allow-import
CMD [ "deno", "task", "run" ]

Additional Issue: Docker Network

If CouchDB runs in a separate container, the bridge cannot reach localhost:5984 due to Docker network isolation.

Solution: Add network_mode: host to docker-compose.yml:

services:
  bridge:
    build: .
    volumes:
      - ./data:/app/data
      - ./dat:/app/dat
      - /path/to/vault:/path/to/vault
    network_mode: host
    restart: unless-stopped

Environment

• Deno: 2.3.1
• Docker: 24.x
• OS: Debian 12

I hope this helps others facing the same issue
