This is follow up series:
What is Docker container https://www.docker.com/resources/what-container
In simple container is an image or package that will have binaries, configurations etc of the application to run on. Example – In a single OS you can run multiple containers, like CentOS SQL 2017 and 2019 version etc. It is very easy to install, once the image pulled and stored locally, creating SQL server is in a seconds, the advantage is you can create your own images based on the organization standards and store it in Docker HUB. Docker is a container engine developed by Docker to run a containers.
Being SQL server database administrator, mostly we will not worked on Linux platform, I have supported Oracle couple of years and have knowledge of Linux platform.
Following is the 6 steps we are going to test and do ourselves in laptop.
- Install VMware workstation and CentOS
- Install SQL server on Linux CentOS
- Create and install multiple Docker SQL server
- Create volumes with persist data for SQL server database files
- Customize base SQL server image with Docker file
Creating customized SQL container based the organization standard and push to Docker hub.
Create multiple container from Docker file template by using custom SQL server images.
Create multiple SQL server containers creation by using Docker compose with YML script.
- Backup and restore SQL server databases from Linux to windows
- Create and install multiple Docker container SQL server
Now we are installing and configuring Docker container for SQL server to run on.
Pull SQL image from Docker hub and create a container.
Create a Docker container with SQL server agent enabled.
Try connect it from SSMS into the container SQL from your laptop using the port you specified in the creation.
- Create a test database
- Create a test backup job
