How to upgrade the current D-Laravel.
If your current use environment is very smooth and you have not encountered any problems, you don't need to update it.

If you want to use the latest version, and bug fixes, etc., please read this article carefully,
In order to ensure a smooth upgrade, the following is the recommended way to upgrade D-Laravel.

Please confirm that your docker and docker-compose versions are the latest.
If you run D-Larvel in Production, it is best to use the same environment to test and then update.
Updating the docker version may also cause your current environment to fail to perform smoothly.

1. You can clone the latest version of D-Laravel, or download it from the release.
For example, here I cloned a dlaravel folder named tdlaravel.

git clone https://github.com/DevinY/dlaravel.git tdlaravel

2. Copy the old version of data (database directory) and sites (project directory) to the directory of tdlaravel (do not There are special service numbers such as - or _).
Please confirm that the old version of dlaravel has been disabled first.

3. Enter the tdlaravel directory and start it to see if it is normal.

Please note the database version used by the db service in docker-compose.yml.
For example: the images of mysql 5.7.19 and mysql 8.0.11 are very different.
You cannot directly use my.cnf from the old version of mysql 5.7.19 to mysql 8.0.11
In addition, the directory of data in the yml configuration file also needs to be changed, such as data8.

 db:
  image: mysql:8.0.11
  hostname: db
  ports:
    - "127.0.0.1:3306:3306"
  volumes:
    #- ./etc/mysql/my.cnf:/etc/mysql/my.cnf
    - ./data8:/var/lib/mysql
  environment:
   #- MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD-secret}
   - MYSQL_ALLOW_EMPTY_PASSWORD="yes"
   -TZ=Asia/Taipei
  networks:
    - dlaravel_net

4. If it is normal after you update, you can disable tdlaravel first.
Change the existing dlaravel directory to dlaravel-old
Then change tdlaravel to dlaravel.
