You will view Redis logs in the Syslog by querying journalctl and also by viewing the log file itself.

You will install the Redis server, and configure logging to the Syslog.

Redis offers built-in support for logging with Syslog. The logging of the application is the primary source of this information. If you administrate applications and services, you typically want to discover information about the system service status. Redis is a NoSQL database and is based on key-value storing. If you have any problems with or questions about this image, please contact us through a GitHub issue.Redis is one of the most popular in-memory databases.

See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.

Postfix docker syslog software#

However, most software doesn't have an issue with this, so this variant is usually a very safe choice. The main caveat to note is that it does use musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements. This variant is highly recommended when final image size being as small as possible is desired. This image is based on the popular Alpine Linux project, available in the alpine official image.ДЄlpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
