使用端口 80 部署标准容器时，IBM Cloud Code Engine 修订失败

Question

I am trying to deploy an app in a Code Engine project . The container image is pretty standard: docker.io/library/httpd . All I did in the configuration wizard is to change the port from Code Engine default 8080 to port 80.

Code Engine comes back with:

Revision failed to start with "exit code 1". Check your image and configuration.

In the logs I found these two lines:

(13)Permission denied: AH00072: make_sock: could not bind to address [::]:80
(13)Permission denied: AH00072: make_sock: could not bind to address 0.0.0.0:80

Why?

Answer 1

I don't know the answer to your question "why", except I see some people on Stackoverflow mention the range up to 1024 is reserved by the OS. I could run my httpd locally on port 80, but in the IBM Code Engine I had to change to 8080.

This is how I managed to get it running:

I edited the httpd.conf as this post implies:

"There is a hint on how to do this at the DockerHub page. An alternative config file must be obtained and added to the container via the Dockerfile.

First get a copy of the config file:

docker run --rm httpd:2.4 cat /usr/local/apache2/conf/httpd.conf > my-httpd.conf

Then edit the my-httpd.conf file and modify the port:

Listen 8080

Finally add to the Dockerfile the instruction to copy it:

COPY./my-httpd.conf /usr/local/apache2/conf/httpd.conf "
