i build the image using setenforce 0; docker build -t ccp-apache-php-fpm .
If i log into the docker image and run flyway manually it works. i log into image using

UPDATE
I have moved the flyway set up to post install in the docker composer file. problem i have now is it runs continuously and the container keeps restarting

I am working on a Springboot project with docker. I tried to mount volume so I could have access to generated files from the Springboot application in my local directory. The data is generated in the docker container but I can not find it the local directory.
I have read many topics but none seems to be helpful.
Please, I am still new to docker and would appreciate suggestions to assist.
I have tried to mount the volume directly in the dockerfile as there is a docker compose file to run the service alongside others. Below is what I have in my Dockerfile and docker-compose
Dockerfile

The problem here is that you are mounting the same folder ./logs twice. Docker-compose volume mount syntax is - <your-host-path>:<your-container-path>. Also, its better to use relative paths when you are building the application. So change docker-compose file to (assuming you want to see the files in ./target relative to the Dockerfile:
myprofile-backend:
extra_hosts:
- remotehost
container_name: samplecontainer-name

expose:

volumes:

I am trying to run a bash script (install.sh) after the container is created to run apt-get update install wget etc, but the php container fails when I try to run it.
My bash script is:
#!/bin/bash
mkdir testdir && apt-get update && apt-get install wget -y
(this file is here: ./src/install.sh)
It creates the folder correctly and the logs suggest it is trying to install wget (but never seems to finish) but the container never starts correctly.
If I remove the command: /bin/bash -c "./install.sh" line everything works correctly (but wget is not installed).
I have tried moving the command to a Dockerfile as a RUN command but it never seems to run
Any ideas why this is happening?
Thanks
As Hans Kilian said in the comments, docker-compose commands replace anything set by CMD or ENTRYPOINT. These commands are necessary for the container to function, and thus it never does anything more than installing wget.
You appear to be trying to run a file located under "./install.sh," which is not an absolute path. Try running the command using the absolute path of the file, as dockerfiles do not, in my experience, recognize changing directory after each command, so:
RUN cd /xyz
RUN /bin/bash -c "./install.sh"
does not have the same result as
RUN /bin/bash -c "/xyz/install.sh"
(where /xyz is the directory where install.sh is located)
Additionally, make sure the file is marked as executable with chmod when it is copied into your container.
However, if all you desire to do is create a directory and install wget, I would simply do this in the Dockerfile:
RUN mkdir testdir
RUN apt-get update && apt-get install -y wget
I'm getting

You trying to run docker container inside of the docker container. In most cases it is very bad approach and you should to avoid it. But in case if you really need it and if you really understand what are you doing, you have to apply Docker-in-Docker(dind).
As far as I understand you, you need to run script CREATE DATABASE elitypescript, the better option will be to apply sidecar pattern - to run another one container with PostgreSQL client that will run your script.
Link the containers together and connect using the hostname.
# docker-compose
services:
app:
links:
- database
...
then just:
# entrypoint.sh
# the database container is available under the hostname database
psql -h database -p 3030 -U postgres -c "CREATE DATABASE elitypescript"
Links are a legacy option, but easier to use then networks.

And this is my web.dockerfile:
FROM httpd:2.4
COPY httpd.conf /etc/httpd/conf/httpd.conf
When I run docker-compose up shows some messages:
app_1 | AH00526: Syntax error on line 119 of
/etc/httpd/conf/httpd.conf: app_1 | DocumentRoot '/var/www/html'
is not a directory, or is not readable
adsist-docker_app_1 exited with code 1
/var/www/html set as apache documentroot is popular in most linux distributions, but this is not the thing in httpd docker image. Additional, even you modify http.conf to use /var/www/html, you still should mount to /var/www/html, not /var/www.
And back to the httpd image, you could see next:
$ docker run -idt httpd:2.4
docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
182c63e24082 httpd:2.4 "httpd-foreground" 3 seconds ago Up 1 second 80/tcp clever_bassi
$ docker exec -it clever_bassi /bin/bash
root#182c63e24082:/usr/local/apache2/conf# cat httpd.conf
......
DocumentRoot "/usr/local/apache2/htdocs"
......
So, if you do not change default settings, you should mount your host's files to /usr/local/apache2/htdocs to serve your service.
And more, COPY httpd.conf /etc/httpd/conf/httpd.conf in your Dockerfile is also not correct, it should be COPY httpd.conf /usr/local/apache2/conf/httpd.conf.
It seems that your app will be deployed in /var/www/ while you configure Apache to use /var/www/html/ as a document root so while starting Apache it checks first for configured document root but it can't find it so it fails to start and generate the mentioned error.
So you have to decide to change document root in httpd.conf to point to /var/www/ or configure docker-compose file to work and mount volumes to /var/www/html.
I have an up and running containers and I wish to execute a database backup. Apparently, a simple command from the docker such as: sudo mkdir new_folder result in: bash: sudo: command not found
What have I tried (on an intuitive level) I accessed one of the running container with docker exec -i -t 434a38fedd69/bin/bash and RUN
apt-get update
apt-get install sudo
when exit back to docker and tried to perform sudo mkdir new_folder but I got the same message bash: sudo: command not found
Baresp#adhg MINGW64 /c/Program Files/Docker Toolbox/postgre
$ mkdir new_folder
mkdir: cannot create directory ‘new_folder’: Permission denied
Baresp#adhg MINGW64 /c/Program Files/Docker Toolbox/postgre
$ sudo mkdir new_folder
bash: sudo: command not found

First, nothing you do in a docker exec is persistent outside of that particular running container (copy of the image), so if you want future containers run from that image to include sudo, those apt-get commands need to go into the Dockerfile that builds the image. Which, since you're using docker-compose, would require you to first make a Dockerfile and specify its location in the YAML.
Second, what do you mean "exit back to docker"? Nothing you do inside a container is going to have any effect on the system that Docker itself is running on, but it looks like you're running software install commands inside a Docker container and then expecting that to result in the newly-installed software being available outside the container on the Windows system that is running Docker.
To do a backup of the postgres database in the container, you first have to enter the container (similar to how you do it):
docker exec -it postgres bash
(substitude postgres with the real container name you get from docker-compose ps)
Now you are in the container as root. That means, you don't need sudo for anything. Next create your backup folder:
mkdir /tmp/backup
Now run the backup command, from a quick Google I found the following (you might know better):
pg_dumpall > /tmp/backup/filename
Then exit the shell within the container by typing exit. From your host system run the following to copy the backup file out of the container:
docker cp postgres:/tmp/backup/filename .
(postgres is your container name again)
