Dockerfile for running SQL Server with SQL Agent enabled

Dockerfile

# Usage: 
# Ensure Docker daemon is running, then run from the same directory as this Dockerfile: 
#
#   docker build -t my-mssql-server .
#   docker run -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=Yourstr0ngp@ssword' -p 1433:1433 --name sql1 -d my-mssql-server
#
# This builds the image. Then execute the following SQL on the server in SSMS to enable SQL Agent:
#
#   EXEC sp_configure 'show advanced options', 1;
#   EXEC sp_configure 'Agent XPs', 1;
#   RECONFIGURE;
# 
# Data in this database won't be persisted; see Microsoft's quickstart documentation below for guidance on how to 
# persist data between sessions (also: how to generate dumps, query using sqlcmd, etc)
# 
# This Dockerfile is based on Microsoft's FTS example in the mssql-docker repository
# https://github.com/microsoft/mssql-docker/blob/80e2a51d0eb1693f2de014fb26d4a414f5a5add5/linux/preview/examples/mssql-agent-fts-ha-tools/Dockerfile
