A more popular approach is to use external mount points either on the local host or over a network.

Containers are being put into production use on Linux, and as they mature on Windows we can expect increased production usage, particularly as production workflow support is further developed.Įach container has a private file system, and databases run in the local file system are “in container.” This works well for smaller databases (each container with a copy of the data), but changes in the database are lost when the container is deleted. There are also expanding options for support of the data environments, including in-container, mounted, and cloned. Databases are not suited for this approach, and Docker is evolving to support the needs of stateful enterprise apps.įirst, the relatively short-lives of database environments in development and test, and many reporting/Bi uses, are a good fit for database containers. Docker was designed for stateless applications and horizontal scalability, with containers deleted and replaced as needed. It’s common to hear debates over the suitability of Docker for stateful apps. Where private data centers may reach 30% utilization with virtualization, use with containers can double that or more. A sample dockerfile begins with a reference to an image (in this case mssql-2012), and then a network attached database is mounted, and finishes by running a data masking script on the database.ĭocker is known for speed, as containers are delivered in seconds (sometimes less), for assured compatibility when images are shared, and for increased system utilization. NET and Java development, and is growing in popularity for provisioning database environments.Ī dockerfile can add databases or scripts, yielding a modified image that is used for testing. This workflow has become incredibly popular for. A container is created using a >docker run command on the “new_image” (step 4). The Docker design includes a supervisory “daemon” (or Windows Service), Dockerfiles, a DockerHub image registry, as well as locally stored images, and containers.Īn image is built referencing a dockerfile (step 1), which pulls the details of the source image from a local cache (step 2), and on completion is saved as a local “new_image” (Step 3). Docker images are also immutable and contribute to Data Governance, which we’ll cover later in this series. An image is immutable and portable, providing guaranteed compatibility when shared. The workflow begins with a Dockerfile that is a plain text configuration file that defines an image or container. Docker now enjoys industry-wide support from Red Hat, Google, AWS, Microsoft, and hundreds of other firms.ĭocker is an elegant design for application run times, as well as packaging, distribution, and management. The concept surged in popularity with the Docker open source project in 2013 and has become one of the most popular open source projects ever.

The series will be interesting to Developers, DBAs, Data Governance, Architects, and IT decision makers. This is the first in a series of articles on Docker, it’s use for Development and Test, Reporting, and Data Governance. Microsoft has joined the fray with Docker as a feature of Windows Server 2016 and Windows 10, and SQL Server 2017 Linux containers. It’s not widely known, but MySQL, Postgres, and NoSQL are among Docker’s most popular images. The industry is buzzing about Docker Containers and their rapid adoption.
