fish-speech/docker/Dockerfile

# docker/Dockerfile

# IMPORTANT: The docker images do not contain the checkpoints. You need to mount the checkpoints to the container.

# Build the image:
#   docker build \
#       --platform linux/amd64 \
#       -f docker/Dockerfile \
#       --build-arg BACKEND=[cuda, cpu] \
#       --target [webui, server] \
#       -t fish-speech-[webui, server]:[cuda, cpu] .

# e.g. for building the webui:
#   docker build \
#       --platform linux/amd64 \
#       -f docker/Dockerfile \
#       --build-arg BACKEND=cuda \
#       --target webui \
#       -t fish-speech-webui:cuda .

# e.g. for building the server:
#   docker build \
#       --platform linux/amd64 \
#       -f docker/Dockerfile \
#       --build-arg BACKEND=cuda \
#       --target server \
#       -t fish-speech-server:cuda .



# Multi-platform build:
#   docker buildx build \
#       --platform linux/amd64,linux/arm64 \
#       -f docker/Dockerfile \
#       --build-arg BACKEND=cpu \
#       --target webui \
#       -t fish-speech-webui:cpu .


# Running the image interactively:
#   docker run \
#       --gpus all \
#       -v /path/to/fish-speech/checkpoints:/app/checkpoints \
#       -e COMPILE=1 \ ... or -e COMPILE=0 \
#       -it fish-speech-[webui, server]:[cuda, cpu]

# E.g. running the webui:
#   docker run \
#       --gpus all \
#       -v ./checkpoints:/app/checkpoints \
#       -e COMPILE=1 \
#       -p 7860:7860 \
#       fish-speech-webui:cuda

# E.g. running the server:
#   docker run \
#       --gpus all \
#       -v ./checkpoints:/app/checkpoints \
#       -p 8080:8080 \
