Compose fails if book uses Mermaid

[cusma]

Using the suggested compose.yml with a book that uses mdbook-mermaid, docker compose up fails with the following error:

[+] Running 1/0
 ✔ Container mdbook  Created                                                                                                                                                                                                                     0.0s

I have updated the instructions. We need the mermaid.min.js at the same level as book.toml.
Please refer to the example project.

cd ./example

# Run "mdbook serve"
docker compose up

# Run "mdbook build"
docker compose run --rm mdbook build

We can also consider the following.

• Add assets to docker image like mermaid.min.js #130

I think this would be the best approach.
