no80 - The resource effective redirecting http server
No80 is a minimal dockerized http server that only makes redirects temporarily (302) or permanently (301)to given URLs. Often used to redirect http service users to a https service. A way more simple way to dohttp redirects than, for example, nginx. The docker image size is under one megabyte.
Docker repository is available athttps://hub.docker.com/r/malafoss/no80.
To run the latest container:
<docker|podman> run <DOCKER_OPTIONS> -p <PORT>:80 docker.io/malafoss/no80 <OPTIONS> <URL>Options:
-a Append path from the http request to the redirected URL -h Print this help text and exit -m PATH URL Redirect path matching with PATH to URL -s PATH URL Redirect path starting with PATH to URL -r PATH URL Redirect path starting with PATH to URL appended with the rest of the path -p N Use specified port number N (default is port 80) -P Redirect permanently using 301 instead of temporarily using 302 -q Suppress statisticsWith-P option, no80 will make permanent http redirects using301 and without-P option using302.
Example 1:
podman run -t -i --rm -p 8080:80 docker.io/malafoss/no80 https://example.comRuns no80 http server which will redirect all port 8080 requests tohttps://example.com.
Example 2:
podman run -t -i --rm -p 8080:80 docker.io/malafoss/no80 -a https://example.comRuns no80 http server which will redirect port 8080 requests having request path/path tohttps://example.com/path.
Example 3:
docker run --userns host --network host -t -i --rm docker.io/malafoss/no80 -a https://`hostname -f`or
docker run -t -i --rm -p 80:80 docker.io/malafoss/no80 -a https://`hostname -f`Redirect browsers accessing http port 80 to https port 443 on the current host.
Example 4:
podman run -t -i --rm -p 8080:80 docker.io/malafoss/no80 -m /match https://siteA/pathA https://siteB/pathBRedirect browsers accessing http port 8080 tohttps://siteA/pathA if request path matches with/match. Otherwise browsers are redirected tohttps://siteB/pathB.
Example 5:
podman run -t -i --rm -p 8080:80 docker.io/malafoss/no80 -m /match https://siteA/pathA -s /starting https://siteB/pathB -r /redirect https://siteC/pathC https://siteD/pathDRedirect exact path/match tohttps://siteA/pathA.Redirect paths starting with/starting such as/starting/mypath tohttps://siteB/pathB.Redirect paths starting with/redirect such as/redirect/mypath tohttps://siteC/pathC/mypath.Otherwise redirect by default tohttps://siteD/pathD.
Note that multiple-m,-s and-r options are allowed and are processed in the given order.
