Send a HTML or Mustache template and recieve a PDF stream as the response.
Navigate to quay.io/ukhomeofficedigital/html-pdf-converter to find latest the tagged version. Docker will pull whichever version you specify.
For example, if the latest tagged version v2.4.3 then this command will need to be run:
docker pull quay.io/ukhomeofficedigital/html-pdf-converter:v2.4.3 Once completed you can check the image is available locally by running:
docker image listAll HOF forms run locally on port 8080 and in some cases port 8081 may also be in use; so the html-pdf-converter should be run on another port. Currently port 8082 is recommended.
docker run -t -i -p 8082:8080 quay.io/ukhomeofficedigital/html-pdf-converter:**<tag>**Observe following in terminal:
2023-09-13T11:18:07.061Z - info: Listening on localhost:8080Note: The terminal will say that the application is listening on port 8080, however you can verify which port the html-pdf-converter container is using by running:
docker ps -aThe Node app that is using the html to pdf converter will need to be run locally too. The service will need the following env variable:
-
PDF_CONVERTER_URL: If you are running a local PDF converter this is the url and port it is running on. This URL should be in the formatPDF_CONVERTER_URL=http://localhost:<PORT>/convert. -
In this example the PDF_CONVERTER_URL would be
PDF_CONVERTER_URL=http://localhost:8082/convert
Upon a successful html to pdf conversion the response should look something like this:
2023-09-12T15:31:30.249Z - info: status=201, method=POST, url=/convert, response_time=392, content_length=39644git clone [email protected]:UKHomeOffice/html-pdf-converter.git
