Development Information¶
Makefile¶
The important command lines for development are collected in the Makefile.
Docker Environment¶
The rsensor-Docker-Container contains the following components:
- Mysql Server
- the database is initialized with the script
test/init_db.sql
- the database is initialized with the script
- sqlite3
- Python
- the latest rsensor package (todo: really needed?)
- (todo: maybe add mosquitto)
The Container is created with the command:
cd test
docker build -t rsensor .
The container is started with:
cd test
docker run --rm --name rsensordb --hostname rsensordb -v $(pwd):/test -p 5555:5000 -p 3306:3306 -t -i rsensor
Options:
| –rm: | delete container at exit |
|---|---|
| –name ….: | set container name |
| –hostname ….: | set hostname of the container |
| -v …: | map local directory as volume |
| -p …: | map ports to host system |
| -t: | ??? |
| -i: | ??? |
| rsensor: | name of the container (see docker build) |
At the docker-prompt you can testwise access the database:
mysql -u root
The script prepare_mysql.sql creates the user rsensor and the database rsensor:
mysql -u root < prepare_mysql.sql
Using the MySQL Docker DB from extern¶
Acess the container via its IP address with:
mysql -u rsensor -h 172.17.0.1 rsensor -p
The password is “rsensor” (see prepare_mysql.sql)
