Error when trying to run monero-wallet-rpc with docker-compose up

Question

I provide user and password in config file, but I got the error as it tries to create .login file. When I run for the first time it runs without restriction, but when I run for the second time, it throws error.

docker-compose up Starting monerodocker_monero_1 ...

Answer 1

I had the exact same error message when running monero-wallet-rpc without the option --disable-rpc-login.

Then, as explained by vtnerd in this open issue:

The file is always created in the current working directory when authentication is enabled.

To create the file, you need to be the owner of the working directory.

I set the current user within the docker container as the owner of the working directory, so Check permissions disappeared and monero-wallet-rpc started correctly.

By the way:

When leaving --disable-rpc-login you should provide --rpc-login user:password.
