Microsoft SQL Server Express is a version of Microsoft's SQL Server
relational database management system that is free to download,
distribute and use. It comprises a database specifically targeted
for embedded and smaller-scale applications.
SQL Server Express Edition is a scaled down, free edition of SQL Server, which includes the core database engine. While there are no limitations on the number of databases or users supported, it is limited to using 1 processor socket, 1 GB memory and 10 GB database files.
More information about the differences between SQL Server editions can be found on the Microsoft website.
To deploy a MSSQL Express service:
juju deploy cs:~cloudbaseit/mssql-express --series <supported_windows_series>
version - Choose the SQL Server Express version to be deployed. Supported
versions: 2012, 2014. The installer specific to the version is downloaded
from the Internet, checked for integrity with SHA1 checksum and then
sa-password - Password used by the System Administrator special login.
installer-url - If provided, it overrides the default download url for the
MSSQL installer. This should be provided, for example, when the MSSQL
installer is found somewhere on a local web server.
NOTE: version and installer-url won't change anything
in the charm if dynamically changed. This values are used only in the install
hook, when service is installed.
SA password can be dynamically changed by:
juju set mssql-express sa-password=Password123
NOTE: sa-password must respect the minimum complexity policy enforced by Microsoft.
