![]() ![]() ![]() The problem with this is that not everyone is savvy enough to analyze complex files in the terminal.Ģ) Have the logs on each host shipped to a single server where we can review all the logs in 1 place. Now that we have the logs in a file, there are a couple of ways I have in mind for how we can simplify the process of reviewing the logs.ġ) Log in to each host and view the log files directly (without using the docker logs command). ![]() If you do not understand why I am excited, let me explain to you some of the possibilities that now exist because of this discovery. If you’re into or want to explore that kind of stuff, check out the docker documentation here.ĭid this discovery turn on the lightbulb above your head yet? Docker can be customized to use different log drivers that store the logs in different formats. On Linux machines, the logs are stored in “/var/lib/docker/containers/*/*.log “. What if I told you that the logs are stored somewhere on your host machine?īecause containers are stateless, the container logs are stored on the host and in JSON files by default. What if I told you there are better ways to manage this?Įver wondered where Docker logs from running the “docker logs” command are stored? Management: Without a proper log management system in place, it can be difficult to collect, store, and analyze the logs from multiple containers and hosts. Searching and Filtering: Searching and filtering through large volumes of logs can be very challenging, especially without a proper log management system in place. Retention and Archiving: Keeping old logs for a long time can consume a lot of disk space which can become expensive and can make searching through logs difficult. Volume: With many containers running on a single host or across multiple hosts, the volume of logs generated can quickly become overwhelming, making it difficult to find the information you need.Īccessibility: If you need to access logs from different hosts, you may have to log in to each host separately, which can be very time-consuming and prone to human error.Īlerting and Monitoring: Without proper alerting and monitoring, important logs may (rather, will!) go unnoticed, leading to potential issues or security breaches. Why did the headline grab your attention? Is it because of any of the below: Problems with managing Docker logs through the CLI First of all, what challenges do you have with managing Docker logs through the CLI? ![]()
