Solo docker run - documentation clarity

[miketwenty1]

Describe the bug
Trying to run RTL with minimum configuration in docker

To Reproduce
docker run -d --name rtl -p 3001:3000
-e LN_SERVER_URL=https://LND_NODE_IP:8080
-e LN_IMPLEMENTATION=LND
-v /path/to/macroon:/root/.lnd/data/chain/bitcoin/mainnet/
shahanafarooqui/rtl:0.11.1

Tried using the MACAROON_PATH environment variable but it seemed to not be used and I got errors which made me mount the macaroon to /root/.lnd/data/chain/bitcoin/mainnet/ as it was being looked for there.

Not sure what to do with HOST environment variable. It's not clear to me how to run this solo without errors.
After resetting password I get errors in the ui and in the docker logs.

docker logs rtl
Start...config creation at: /RTL/RTL-Config.json
End...config creation.
Please note that, RTL has encrypted the plaintext password into its corresponding hash.
Server is up and running, please open the UI at http://localhost:3000

@miketwenty1 Can you please post your variables here?

[miketwenty1]

based on what you mentioned we need 4 key environment variables

docker run -d --name rtl -p 3001:3000 \
-e LN_SERVER_URL=https://LND_IP:8080 \
-e RTL_SSO=0 \
-e RTL_CONFIG_PATH=/RTL \
-e MACAROON_PATH=/path/to/macaroon \
-v /path/to/macaroon:/root/.lnd/data/chain/bitcoin/mainnet/ \
shahanafarooqui/rtl:0.11.1

[ShahanaFarooqui]

What is your rtl root? you need to provide the full RTL path for the RTL_CONFIG_PATH variable. What does -v /path/to/macaroon:/root/.lnd/data/chain/bitcoin/mainnet/ do? Do we need this line after configuring MACAROON_PATH variable?

[miketwenty1]

i've never used github discussions like this.. didn't know what you meant before

[saubyk]

Its a new GitHub feature. Not a lot of people are aware. :-)

Below is the minimal working example to run solo RTL app within docker container:

Step 1: Create a .env file in local RTL root and assign values to variables:

    LN_SERVER_URL=https://host.docker.internal:8080
    RTL_CONFIG_PATH=/RTL
    MACAROON_PATH=/lnd-macaroon

Step 2: Build docker image locally with below command:

    docker build -t rtl:0.0 .

Step 3: Run docker image with below arguments:

    docker run -d --mount type=bind,source=<local-source-path>,target=<docker-mount-path, example:/lnd-macaroon> --env-file=.env -p 3005:3000 rtl:0.0

Step 4: Open the app in the browser with url http://localhost:3005/rtl.

Please note that it is just a minimal example and can be modified/adjusted according to the user's requirement.

Feel free to refer to advanced settings from docker/docker-compose.yml to build and run your application stack with docker-compose.
