Run php command inside bash script inside Docker container with ubuntu image-CodePudding

I have a bash script and a php script.

--------EDIT-------- I SOLVED IT, I AM JUST STUPID, I WROTE MY ANSWER BELOW.

(I can put code screenshots if you want.)

MY DOCKERFILE:

ARG VERSION=latest
FROM ubuntu:bionic
RUN apt-get -y update && apt-get -y upgrade
COPY ./resources/ start.sh /sandbox/
WORKDIR /sandbox/
ENTRYPOINT ["sh","start.sh"]

I want to execute them in a docker container as i said in the title.

The 'entry point' of the docker container is the bash script.

Inside the bash script i have a line

php PHP_SCRIPT.php

But when i execute, it gives me the error:

PHP_SCRIPT.php: php: not found

or something like that

i saw that the php command usually resides in '/usr/bin/php', but i tried to run the command 'which php' in the docker container and the result was '/usr/local/bin/php'

Maybe i am calling the php command wrong?

But the result that i want is to run a php script INSIDE a bash script that starts when i start the docker container.

You are using the docker image FROM ubuntu:bionic which does not have PHP installed by default. Try FROM php (or one of the many tags available) instead.

CodePudding user response：

the problem is that PHP is not installed in your container To do this, you can use your official PHP image https://hub.docker.com/_/php

FROM php:7.4-cli

ARG VERSION=latest
RUN apt-get -y update && apt-get -y upgrade
COPY ./resources/ start.sh /sandbox/
WORKDIR /sandbox/
ENTRYPOINT ["sh","start.sh"]

CodePudding user response：

FROM php:7.4-cli
WORKDIR /opt/myapp
COPY myshellscript.sh .
COPY myphpscript.php .
ENTRYPOINT ["./myshellscript.sh"]


$ docker build -t my-image .
$ docker run --rm --name my-app my-image
call php from shellscript
output from php script
sleeping ...

CodePudding user response：

And i would get the "php not found error" because i didnt install php to the docker container.

So, I tried writing in the dockerfile

RUN apt-get php-cli (i also tried with php:cli and seemed to have same effect),

to try to install php to container, but when i would start container it would seem like it would freeze and not do anything.

Apparenty, it doesnt 'freeze', but i only had to wait for the php to update in the container. :D
