Fonts
By default, the Docker image contains many fonts, including Asian ones.
If you wish to use more fonts, you will have to build a Docker image.
.ttf
FROM gotenberg/gotenberg:7
USER root
COPY /local/path/to/{font}.ttf /usr/local/share/fonts/{font}.ttf
USER gotenberg
Or, if you have many fonts:
FROM gotenberg/gotenberg:7
USER root
COPY /local/path/to/fonts/* /usr/local/share/fonts/
USER gotenberg
apt-get install
FROM gotenberg/gotenberg:7
USER root
RUN DEBIAN_FRONTEND=noninteractive apt-get install -y -qq --no-install-recommends my-fonts-package
USER gotenberg
