+# Fooocus on Docker
+
+The docker image is based on NVIDIA CUDA 12.3 and PyTorch 2.0, see [Dockerfile](Dockerfile) and [requirements_docker.txt](requirements_docker.txt) for details.
+
+## Quick start
+
+**This is just an easy way for testing. Please find more information in the [notes](#notes).**
+
+1. Clone this repository
+2. Build the image with `docker compose build`
+3. Run the docker container with `docker compose up`. Building the image takes some time.
+
+When you see the message  `Use the app with http://0.0.0.0:7865/` in the console, you can access the URL in your browser.
+
+Your models and outputs are stored in the `fooocus-data` volume, which, depending on OS, is stored in `/var/lib/docker/volumes`.
+
+## Details
+
+### Update the container manually
+
+When you are using `docker compose up` continuously, the container is not updated to the latest version of Fooocus automatically.
+Run `git pull` before executing `docker compose build --no-cache` to build an image with the latest Fooocus version.
+You can then start it with `docker compose up`
+
+### Import models, outputs
+If you want to import files from models or the outputs folder, you can uncomment the following settings in the [docker-compose.yml](docker-compose.yml):
+```
+#- ./models:/import/models   # Once you import files, you don't need to mount again.
+#- ./outputs:/import/outputs  # Once you import files, you don't need to mount again.
+```
+After running `docker compose up`, your files will be copied into `/content/data/models` and `/content/data/outputs`
+Since `/content/data` is a persistent volume folder, your files will be persisted even when you re-run `docker compose up --build` without above volume settings.
+
+
+### Paths inside the container
+
+|Path|Details|
+|-|-|
+|/content/app|The application stored folder|
+|/content/app/models.org|Original 'models' folder.<br> Files are copied to the '/content/app/models' which is symlinked to '/content/data/models' every time the container boots. (Existing files will not be overwritten.) |
+|/content/data|Persistent volume mount point|
+|/content/data/models|The folder is symlinked to '/content/app/models'|
+|/content/data/outputs|The folder is symlinked to '/content/app/outputs'|
+
+### Environments
+
+You can change `config.txt` parameters by using environment variables.
+**The priority of using the environments is higher than the values defined in `config.txt`, and they will be saved to the `config_modification_tutorial.txt`**
+
+Docker specified environments are there. They are used by 'entrypoint.sh'
+|Environment|Details|
+|-|-|
+|DATADIR|'/content/data' location.|
+|CMDARGS|Arguments for [entry_with_update.py](entry_with_update.py) which is called by [entrypoint.sh](entrypoint.sh)|
+|config_path|'config.txt' location|
+|config_example_path|'config_modification_tutorial.txt' location|
+
+You can also use the same json key names and values explained in the 'config_modification_tutorial.txt' as the environments.
+See examples in the [docker-compose.yml](docker-compose.yml)
+
+## Notes
+
+- Please keep 'path_outputs' under '/content/app'. Otherwise, you may get an error when you open the history log.
+- Docker on Mac/Windows still has issues in the form of slow volume access when you use "bind mount" volumes. Please refer to [this article](https://docs.docker.com/storage/volumes/#use-a-volume-with-docker-compose) for not using "bind mount".
+- The MPS backend (Metal Performance Shaders, Apple Silicon M1/M2/etc.) is not yet supported in Docker, see https://github.com/pytorch/pytorch/issues/81224
+- You can also use `docker compose up -d` to start the container detached and connect to the logs with `docker compose logs -f`. This way you can also close the terminal and keep the container running.
