I download the file, expand the archive then delete the original archive. Here I optimise things by going multi-line with the separator. On Linux the binary can be built easily and/or installed from a distribution's package manager such as apt-get. There is a link to this project from redis.io if you want to check it out. The MSOpenTech project provides a binary for Windows.
The upshot was that I downloaded and expanded a zip file instead.
Because the installation has to be run in silent we miss the fact that Redis also configures a system service overriding any custom configuration.Īfter an hour or so of struggling to find out why my custom config was being ignored I found out about the Windows service. I started off by creating a new Dockerfile - downloading the Redis MSI package and then running in the installation.
It is the de facto installation format and nearly all software is distributed this way. Many Windows users are used to MSI files - they tend to include everything to configure a package and provide a way of removing it cleanly after at a later date. While we are at it - let's set the default shell from cmd to powershell: MSI or not to MSI? Nano Server makes downloading and expanding a file a lengthy and complicated process (around 15-20 lines) where as the traditional PowerShell has various Commandlets such as Invoke-Webrequest to make the complicated simple. Nano also has no support for MSI files - the Microsoft Installer format. Nano server is being pitched as Microsoft's brand-new re-designed operating system - fully 64-bit with a stripped down PowerShell. There are two options for base images: Windows Server Core or Windows Nano Server. The data model is key-value, but many different kind of values are supported: Strings, Lists, Sets, Sorted Sets, Hashes.
Redis is an in-memory database that persists on disk.
Here's how I did it.īefore we begin make sure you are running up updated edition of Windows 10 pro/enterprise or Windows 2016 Server with Docker installed. I've ported several images to Windows so set about creating a new Dockerfile. While I was porting the Docker Voting App to Windows Containers I hit a stumbling block - there was no official image for Redis on Windows. In the cluster node section, you can see the address of the node, 172.17.0.2 in my case. In the container, run the rladminstatuscommand, to get information about your deployment. Install a single node cluster of Redis Enterprise using Docker Create a new cluster Created a database that listens on port 12000. So basically, it is optimized for size, speed and is easy. Furthermore, nearly every official Docker image has a tag for Alpine. This is the best practice for keeping the smallest footprints possible in our application and it also doesn’t include any extra dependencies in the system which may cause unexpected side effects or it may even create security vulnerabilities.Why use Alpine Linux for your Docker container? Alpine makes a great docker container, because it is so small and optimized to be run in RAM. The reason for including these options is to minimize the number of extra files and packages that are added to our docker container.
We’re going add a package by using -update option which means update the registry before adding it and –no-cache option is not storing the registry index on our docker file. In order to interact with Postgres we need to install postgresql-client and to achieve that we can use the package manager that comes with alpine. Next, we are going to install our dependencies by copying our requirements.txt into the docker image then we will run the pip command to start the installation. It also means that there is no partial output in a buffer in case the python program fails. Setting the non-empty value of PYTHONUNBUFFERED means that the python output is transmitted directly to the terminal without being buffered and that allows displaying the application’s output in real-time. Initially, we are using python:3.7-alpine which is a very lightweight image and highly recommended to keep the size as small as possible and usually, it’s safe in terms of compatibility.
