# Python 3.7.4 + pyodbc (SQL Server)
[Docker environment](https://hub.docker.com/r/felipederodrigues/python37withpyodbc) with Python 3.7 and pyodbc dependencies installed for connection with SQL Server database.
## Dockerize your Python app using this environment
### Create this Dockerfile (inside your Python app main directory)
```java
FROM felipederodrigues/python37withpyodbc:v1
COPY . /app
WORKDIR /app
RUN pip install --upgrade pip
RUN python -m pip install -r requirements.txt
ENTRYPOINT [ "python", "Main.py" ]
```
### Create a Docker image with it. This image will have your app inside it (e.g.: /app directory).
```java
docker build -t the-name-of-your-image:latest .
```
### Run your app:
```java
docker run the-name-of-your-image:latest
```
## Suggestion
As a good practice, you can feed your app with environment variables for database connection.
For instance, you may call your application like this:
```java
docker run \
-e SQL_SERVER_SERVER="hostname.your.network" \
-e SQL_SERVER_DATABASE="YourDatabaseName" \
-e SQL_SERVER_USERNAME="YourDatabaseUsername" \
-e SQL_SERVER_PASSWORD="YourDatabasePassword" \
the-name-of-your-image:latest
```
And the code may pick this information up, without hardcoding credentials.
```python
@staticmethod
def connect_db():
"""
Parameters
----------
"""
print("Conecting to database ...")
server = os.environ['SQL_SERVER_SERVER']
database = os.environ['SQL_SERVER_DATABASE']
username = os.environ['SQL_SERVER_USERNAME']
password = os.environ['SQL_SERVER_PASSWORD']
return db.DBConnection(server, database, username, password)
```
