How to fix "Could not find datomic in catalog"

I'm trying to run datomic pro using a local postgresql, transactor an peer.

I'm able to start both the database and the transactor without any problem:

db-storage       | 2019-09-01 21:26:34.823 UTC [1] LOG:  starting PostgreSQL 12beta3 on x86_64-pc-linux-musl, compiled by gcc (Alpine 8.3.0) 8.3.0, 64-bit

db-transactor    | System started datomic:sql://<DB-NAME>?jdbc:postgresql://localhost:5432/datomic?user=datomic&password=datomic-password, you may need to change the user and password parameters to work with your jdbc driver

(They're all running on containers with a network_mode=host) I think that theses warnings may come from the fact that I'm using datomic as the user and the database name, but I'm not sure.

But then, when I try to start a peer server, I'm faced with the following error:

$ ./bin/run -m datomic.peer-server -h localhost -p 8998 -a datomic-peer-user,datomic-peer-password -d datomic,datomic:sql://datomic?jdbc:postgresql://localhost:5432/datomic?user=datomic\&password=datomic-password

    at clojure.main.main(main.java:37)

I've already tried changing a bunch of configurations with no success. Can someone help me?

I faced with the same issue but I've found a solution after carefully docs exploring.

The key is presented in this section of the documentation: https://docs.datomic.com/on-prem/overview/storage.html#connecting-to-transactor

After running a transactor and before you run a peer, go to datomic base dir and execute following:

bin/shell

## for now you are inside datomic shell

uri = "datomic:sql://datomic?jdbc:postgresql://localhost:5432/datomic?user=datomic&password=datomic";

Peer.createDatabase(uri);

## Terminate your datomic shell

That's all. After that you can run peer server as you mentioned
