emask-tax-docker

Introduction

• This is a Docker image repository for building emask and tax systems. (口罩預購系統與線上報稅系統)
• It includes some features and they're as follows:
  • EZ100PU card driver
  • pcsc_scan and car scanner tool
  • A NHIIC client daemon. (It's for Taiwan Health Card)
  • A Personal certificate card client daemon. (It's for MOICA Citizen Digital Certificate of Taiwan R.O.C. (PKI)
  • Firefox web browser. The version is 75.0. (It's deprecated because the Firefox web browser usually have unexpected core dumped frequently....)
  • Google Chrome web browser. (The current stable version is 81.0.4044.122 at this time.)

Usage

• Using following command to download Docker image:

docker pull peter279k/emask-tax-docker:latest

• Download the start.sh from this repository and it can run this command:
• Then execute ./start.sh directly.
• It will present the Google Chrome web browser window and have three tabs about following URLs:
  • https://emask.taiwan.gov.tw/msk/index.jsp
  • https://tax.nat.gov.tw/alltax.html?id=1#
    • This URL should let user trust this certificate and add this on certificate manager manually because it's for NHIIC client daemon.
• And enjoy it!

Repository file structures

• docker_build.sh, a bash shell script and the usage is as follows:
  • ./docker_build.sh, run Docker image building with cached Docker building steps,
  • ./docker_build.sh --no-cache, run Docker image building from first steps to last steps on Dockerfile.
• NHIICC_Install.sh, this will be executed during Docker image building and it's part of NHIICC client daemon installation.
• run.sh, this bash shell script will be copied to Docker image and it's the entry point during Docker container running.
• start.sh, this bash shell script can help user to execute Docker image as container easily. And it can execute this script directly.
• smartcard_list.txt, this bash shell script is to let pcscd card scanner be easy to identify plugged card information.

Trouble Shooting

• It will happen known error I found:
  • The Firefox web browser will be closed unexpectedly with core dumped at some moments.
    • This will not happen because this Docker image uses the Google Chrome web browser instead.
  • The error message is as follows:

......
line 43:    40 Bus error               (core dumped) firefox ${emask_url} ${tax_url}
......

• This is not usual error, and it doesn't have current solution to be resolved.
• At this moment, the current solution is to run ./start.sh again.
• If this error happens frequently, I recommend using ./start.sh google-chrome-stable to execute Google Chrome web browser.
• Another known error is as follows:

......
PC/SC device scanner
V 1.5.2 (c) 2001-2017, Ludovic Rousseau <ludovic.rousseau@free.fr>
Using reader plug'n play mechanism
Scanning present readers...
Waiting for the first reader...
......

• This above error happens because the card device scanner is not detected or lost scanning connection from PC/SC device scanner.
• The current solution is:
  • Firstly, close the web browser and ensure the Docker container is not running.
  • Secondly. Unplugging the card reader device and plugging this device again.
  • Lastly, running the ./start.sh shell script again and let Docker container be restarted again.
  • If it presents following message, it will be successful to resolve card device reader scanning/detecting issue.

  • /tmp/HiPKILocalSignServerApp.log
  • /tmp/NHIICC.log
