walter@ubuntu:/mnt/hgfs/Projects/docker_images$ tesseract *.pdf output

Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.

1. tesseract --list-langs only print filenames in TESSDATA_PREFIX - e.g. it does not guarantee that files are not corrupted or they are compatible with your tesseract version
2. tesseract without specification of language (-l) expect to find "eng". Your setting provides "tessdata/eng" (see information you provided) e.g. you either provide option "-l  tessdata/eng" or you set TESSDATA_PREFIX=/home/walter/tesseract/tessdata (or "--tessdata-dir /home/walter/tesseract/tessdata")
