<!-- Answer -->
To resolve the issue with the `BUILD_TRANSLATIONS` environment variable not
being recognized during the Docker build process, you need to ensure that the
variable is correctly declared in the appropriate Dockerfile stage. The problem
arises because the `ENV` parameter is not propagated across different stages in
a Dockerfile.
Here's a clean solution:
1. Declare the `BUILD_TRANSLATIONS` argument at the beginning of the
Dockerfile.
2. Set the `ENV` variable in each stage where it's needed.
Here's how you can modify the Dockerfile:
```dockerfile
# Declare the argument at the top
ARG BUILD_TRANSLATIONS="false"
# Use the argument in the python-translation-compiler stage
FROM python-base AS python-translation-compiler
ARG BUILD_TRANSLATIONS
ENV BUILD_TRANSLATIONS=${BUILD_TRANSLATIONS}
# Your existing RUN command
RUN if [ "$BUILD_TRANSLATIONS" = "true" ]; then \
pybabel compile -d /app/translations_mo | true; \
fi; \
rm -f /app/translations_mo/*/*/*.json;
```
When building the Docker image, make sure to pass the `BUILD_TRANSLATIONS`
argument:
```bash
docker build --build-arg BUILD_TRANSLATIONS=true -t your_image_name .
```
This setup ensures that the `pybabel compile` command is executed correctly,
generating the `.mo` files as expected

Regarding the placeholder errors in the `.po` files, these are common issues
that occur when placeholders in the translated text do not match those in the
original text. You will need to manually edit the `messages.po` files to ensure
that all placeholders are correctly named and formatted
