PHP:8-Apache Custom-image docker-compose errors over errors

Docker Hub
1

Hello,
I’m currently trying to build Custom images under docker-compose.
I get a lot of error messages and no matter what I install, there are errors.
I suspect something else is wrong with my approach

Maybe someone can help me. I’m still brand new among Docker users

My System is
Raspberry Pi 4
Raspberry original image

PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

i have only a default Raspberry debian 64Bit image i dont have any apache or php instaled
thats mean i don’t have any folders created already on my system maybe what the instaltions need

There are my folders and docker-volume

/home/grobot/docker
looks like that

The Error
cannot open php.ini “/usr/local/etc/php” for writing
is not possible because
i have there 777
ls -la /usr/local/etc/
drwxrwxrwx 3 root root 4096 22. Feb 01:43 php
ls -la /usr/local/etc/php
drwxrwxrwx 2 root root 4096 21. Feb 19:32 conf.d
-rwxrwxrwx 1 grobot grobot 102 22. Feb 02:01 php.ini

After what felt like the twentieth attempt, I had created the php.ini in the directory /usr/local/etc/php and php.ini file myself !!!
I thought it would be better then… but I was wrong

if the error message means
/bin/sh: 1: 2enmod: not found
same same with any freetype error… i installed on my raspberry system this modules already but not interested him

best reagards

Typo? In the next line you use a2enmod, is this supposed to be the same command?

At least, this is what causes this error:

#0 161.5 /bin/sh: 1: 2enmod: not found

Why would that be relevant when building the image? The volume declaration is only used when running a container, not when building an image. Unless you copy the files into the image using a COPY instruction, the files won’t be present in the image, except of course if the files already exist in the base image.

i’m not sure i think rewrite and headers… is that same ?

i use this sample Dockerfile and yaml file from github

but thank’s a lot… i try it and i will tell you the result

Is there an example?
So after creating the image, I first have to create and copy the individual config files

and then I have to specify that in the Dockerfile

Maybe there is a link that documents how to create an image with php and apache

edit:

if i use only a2enmod rewrite
i need then

RUN cp /etc/apache2/mods-available/rewrite.load /etc/apache2/mods-enabled/

too ?
i see it there

but they used rewrite and headers too…
but ok… i think mod headers isn’t important for me

edit:
i found
RUN a2enmod rewrite headers

then i have only one command

So you didn’t notice that I quoted your Dockerfile where you used 2enmod instead of a2enmod?

Sure there is a documentation: https://docs.docker.com/engine/reference/builder/#copy

You might want to make it a habit to lookup unclear instructions in the Dockerfile reference.

5

oh sorry i’m so blind… now i see :frowning:

6

you told me i have to copy the files…

thats mean… all files what i need … like httpd.conf or php.ini
i have to create first the directory and then the files too
because
i install a apache-image.
Thats run, all was ok, but i not found any config-folder like /etc/apache2

is that normal, i have to configure all?

have i to set the user and group rights too?
i’m now not 100% sure but some years ago if i build self a apache-php, i can not remember i have to copy or create there some default path
If i use a other directory, okay yes then sure i have to copy that
or i missunderstood now

Thanks for the link to the docu

Can’t really tell you how the apache base image is designed. I am not using it. I am not using php at all, so I can’t really recommend on php specifics. I have my roots in java :slight_smile:

Typically you have entrypoint scripts in place that modify configuration files based on environment variables (if the maintainer created it,). So it’s always a good starting point to dig through the image description on dockerhub and see whether they suggest how the image should be extended.
