Private Log Viewer

Secure your Docker container logs with password-protected access using Dozzle.

Protect your container logs with password authentication using Dozzle. This inline Docker Compose configuration requires no external files or volume mounts.

​

Implementation Steps

1. Generate Authentication Credentials

   On your local machine, generate a Dozzle user configuration with escaped dollar signs for Docker Compose:

   docker run --rm amir20/dozzle generate \
     --name "Admin Name" \
     --email [e-mail] \
     --password secret \
     admin | sed 's/\$/\$\$/g'
   

   This creates login credentials (username: admin, password: secret) with automatic $ escaping for Docker Compose. The output is ready to paste directly into your configuration.

2. Configure Dozzle in Docker Compose

   Copy the output from step 1 and paste it into your docker-compose.yml:

   services:
     dozzle:
       container_name: dozzle
       image: amir20/dozzle:latest
       environment:
         - DOZZLE_AUTH_PROVIDER=simple
       volumes:
         - /var/run/docker.sock:/var/run/docker.sock
       configs:
         - source: dozzle_users
           target: /data/users.yml
       ports:
         - 8080:8080
   
   configs:
     dozzle_users:
       content: |
         # Paste the output from step 1 here
         users:
             admin:
                 email: [e-mail]
                 name: Admin Name
                 password: $$2a$$11$$JXzfhhgeNnFME75XzGTxKu46K2KI4OAjEL18HodilKkiBIQt8w9ka
                 filter: ""
   

   The configs directive embeds the authentication data directly in docker-compose.yml without needing external files or additional containers.

3. Access Protected Logs

   Once deployed on Phala Cloud, Dozzle will be accessible at:

   https://{app-id}-8080.dstack-{node-name}.phala.network
   

   Replace {app-id} with your App ID and {node-name} with your deployment target. You can also find the endpoint in your CVM’s View Details > Network > Endpoint section.

   Log in with the secrets (or whatever you set in step 1):

   • Username: admin
   • Password: secret

   Only authorized users with valid credentials can view your container logs.

For production environments with advanced requirements, consider using the Loki and Grafana stack for centralized log aggregation, querying, and visualization.
