i did use ""

ok it seems the string you pass in the env variables has to be a uri safe string, after passing the string in https://www.urlencoder.io/ i managed to not get that exception…

yep

Use "" :
CLEARML__HOSTS__MONGO__BACKEND__HOST="mongodb://<user>:<pass>@<hostname>:27017/backend" CLEARML__HOSTS__MONGO__AUTH__HOST="mongodb://<user>:<pass>@<hostname>:27017/auth"

OK, good to know 😄

Will try and update

SharpDove45 , can you try this instead:
TRAINS__HOSTS__MONGO__BACKEND__HOST: "\"mongodb://myDBReader:D1fficultP%40ssw0rd@mongodb0.example.com:27017/?authSource=admin\"" TRAINS__HOSTS__MONGO__AUTH__HOST: "\"mongodb://myDBReader:D1fficultP%40ssw0rd@mongodb0.example.com:27017/?authSource=admin\""

[{{"[" ["^"]} Group:({{Group:({{{{{W:(\, \[]-...) | Re:('\\\\0?[xX][0-9a-fA-F]+')} | Re:('\\\\0[0-7]+')} | !W:(\])} Suppress:("-")} {{{W:(\, \[]-...) | Re:('\\\\0?[xX][0-9a-fA-F]+')} | Re:('\\\\0[0-7]+')} | !W:(\])}}) | {{{W:(\, \[]-...) | Re:('\\\\0?[xX][0-9a-fA-F]+')} | Re:('\\\\0[0-7]+')} | !W:(\])}}}...)}, "]"]is the “grammer” for the parser, and it doesn’t seem to have a literal @ in it… unless i’m missing something

SuccessfulKoala55 So i tried what you suggested but i’m getting
pyparsing.ParseException: Expected end of text, found '@' (at char 56), (line:1, col:57)Any idea whats the issue? i supplied the env variable via docker compose file with the same standard as the one you posted

i tried running the string in config_parser.ConfigFactory() (parse_string) and got the same error

Hi SharpDove45 ,
You mean wou'd like to set up a ClearML Server that will use a remotely-managed mongodb?

Can I see the complete docker-compose.yml you're using?

well no… the parser doesn’t seem to match what the mongo engine expects when passing a uri with username and password, so unless i’m missing something there’s no way to connect to a remote mongo that needs a user/pass to authenticate

So does it work now?

Well, the server's hosts.conf file contains the connection strings for MongoDB (see https://github.com/allegroai/clearml-server/blob/6434f1028e6e7fd2479b22fe553f7bca3f8a716f/apiserver/config/default/hosts.conf#L25 )
You can override it using environment variables in the form of:
CLEARML__HOSTS__MONGO__BACKEND__HOST=mongodb://<user>:<pass>@<hostname>:27017/backend CLEARML__HOSTS__MONGO__AUTH__HOST=mongodb://<user>:<pass>@<hostname>:27017/authFor the two MongoDB databases used by the server

You might need to revert your escaping code (i.e. the use of %40 etc.)
