Cannot start Docker environment: Port 80 in use

[stracker-phil]

Describe the bug

After a recent git pull of this repo, I cannot start the service using docker compose up anymore:

❯ docker compose up        
[+] Running 1/0
 ✔ Container memgpt-letta_db-1  Running                                                                              
Attaching to letta_db-1, letta_nginx-1, letta_server-1
Error response from daemon: driver failed programming external connectivity on endpoint memgpt-letta_nginx-1 (c5c9d18eb7bbb3ddb27d68650f9c3246c25ad7541ed93c8d955c2956ce2185c6): failed to bind port 0.0.0.0:80/tcp: Error starting userland proxy: listen tcp4 0.0.0.0:80: bind: address already in use

The problem is the letta_nginx service that wants to use port 80 of the host machine:

letta/compose.yaml

Line 61 in 80d0748

- "80:80"

Proposed solution:

I would love to have a new .env variable to define the LETTA_PORT for the reverse proxy, instead of hard-coding it to port 80

Sample:

  letta_nginx:
    ...
    ports:
      - "${LETTA_PORT:-80}:80"

Please describe your setup

• Installation source: git clone
• Setup: macOS, running letta locally via terminal & docker compose
