Justin Bertram reassigned ARTEMIS-5146:
---------------------------------------
Assignee: Justin Bertram
> wget command creates duplicate index.html on filesystem
> -------------------------------------------------------
>
> Key: ARTEMIS-5146
> URL: https://issues.apache.org/jira/browse/ARTEMIS-5146
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Web Console
> Affects Versions: 2.37.0
> Environment: Docker image:
> [https://hub.docker.com/r/apache/activemq-artemis]
>
> Reporter: Noah Bailey
> Assignee: Justin Bertram
> Priority: Minor
>
> Requests to the webconsole (localhost:8161) creates a buildup of numerous
> "index.html" files to be created on disk, which appears to slow down and
> sometimes stall the application.
> For some of my deployments, we had configured a healthcheck on the docker
> container for artemis by requesting the root path on the console every 30
> seconds to check if the container was alive or not. Here's an example:
> {noformat}
> artemis:
> image: apache/activemq-artemis:2.37.0
> ...
> healthcheck:
> test: ["CMD", "wget", "-q", "http://localhost:8161/";]
> interval: 30s
> timeout: 10s
> start_period: 60s
> retries: 3
> {noformat}
> After a few months of this, it builds up a large number of files on disk.
> Here's an example of a container that was running for about 2 months:
> {code:java}
> find . -name "index.html.*" | tail -n5
> ./index.html.174545
> ./index.html.174548
> ./index.html.174551
> ./index.html.174552
> ./index.html.174553 {code}
> There are indeed nearly 200K index.html files!
> {noformat}
> find . -name "index.html.*" | wc -l
> 174538{noformat}
> Listing the directory for the app can hang for several seconds, and on
> low-spec boxes perhaps cause IO stalls. It also causes the requests to the
> console to take longer and longer, eventually reaching the 10s timeout I
> specified previously (though others may have different configurations). If
> this happens, it can cause the container to start boot-looping too.
> As a workaround, we've replaced the healthcheck command with a TCP check on
> the jms port:
> {noformat}
> (echo -e 'CONNECT\n\n' > /dev/tcp/127.0.0.1/61616 >/dev/null 2>&1) || exit
> 1{noformat}
