I am new to Docker, I have setup Docker Container on an Amazon Linux box.
I have a docker file which installs tomcat java and a war.
I can see all the installations present in the docker container when I navigate through the container in the exact folders I have mentioned in the Docker file.
When I run the Docker container it says tomcat server has started and I have also tailed the logs so I can see the service is running.
But when I open the host IP URL and 8080 port it says URL can't be reached.
These are the commands to build and run the file which works fine and I can see the status as running.
docker build -t friendly1 .
docker run -p 8080:8080 friendly1
What am I missing here? Request some help on this.

Local setup for kubernetes: Mac OS
Docker for desktop >> kubernetes >> traefik >> Gitea
The gitea is installed in the cluster and exposed as clusterIP service ingresses through treafik which is accessible at http://gitea.local. Everything is butter smooth till here.
The pain:
Now i am creating a dockerfile and using a docker build to build an image. This dockerfile is trying to clone a repository from http://gitea.local. The problem is i am getting connection refused all the times.
RUN mkdir -p apps sites/assets/css \
&& cd apps \
&& git clone http://gitea.local/inviadmin/testing.git
Then i simply tried RUN curl http://gitea.local from inside dockerfile just to debug and got the same:
curl: (7) Failed to connect to gitea.local port 80: Connection refused
if i curl google.com from dockerfile its working. Any help is strongly appreciated.

I tested your dockerfile and here's the outcome
Since the only part you were having issue was the git pull, i chose to use the following lines only.
Notice from the build that how adding entry to the /etc/hosts took effect for the following commands.
If the issue still persists then i suggest you start looking into the gitea container's logs.
I am struggling with permissions on docker volume, I get access denied for writing.
This is a small part of my docker file
FROM ubuntu:18.04
RUN apt-get update && \
apt-get install -y \
apt-transport-https \
build-essential \
ca-certificates \
curl \
vim && \............
RUN curl -sL https://deb.nodesource.com/setup_8.x | bash - && apt-get install -y nodejs

USER $USER
WORKDIR /home/$USER
# Expose needed ports
EXPOSE 3000
VOLUME /data_storage
ENTRYPOINT [ "/scripts/startup.sh" ]
Also a small part of my startup.sh
#!/bin/bash
/usr/share/lib/provision.py --enterprise-seed $ENTERPRISE_SEED > config.json
Then my docker builds command:
sudo docker build -t mycontainer .
And the docker run command:
sudo docker run -v data_storage:/home/user01/.client -p 3008:3000 -itd mycontainer
The problem I have is that the Python script will create the folder: /home/user01/.client and it will copy some files in there. That always worked fine. But now I want those files, which are data files, in a volume for backup porpuses. And as I am mapping with my volume I get permissions denied, so the python script is not able to write anymore.
So at the end of my dockerfile this instructions combined with the mapping in the docker run command give me the permission denied:
VOLUME /data_storage
Any suggestions on how to resolve this? some more permissions needed for the "user01"?
Thanks
I was able to resolve my issue by removing the "volume" command from the dockerfile and just doing the mapping at the moment of executing the docker run:
sudo docker run -v data_storage:/home/user01/.client -p 3008:3000 -itd mycontainer
i want to run a specific version of phpUnit WITHIN a docker container. This container will use a specific version of php. i.e
php:5.6-apache
Its a Laravel application. i have install phpunit via composer on the hostfiles and then used the volume command to transfer this to the container.
my composer.json file has following entry:
"require-dev": {
"phpunit/phpunit": "^5.0"
},
This is my docker run command to run the test on my testdev container:
docker run --rm -it -v ~/Users/mow/Documents/devFolder/testdev:/app testdev_php "php ./vendor/bin/phpunit"
This returns the error:
exec: fatal: unable to exec php ./vendor/bin/phpunit: No such file or directory
i am unclear why it says this because te vendor directory is at the root of my site directory.
this is my dockerfile

I guess the real question is this: what is the correct way to run a phpUnit test within a docker container so that its subject to the php version within that container.
In the Entrypoint, you need to ran composer install to install the requisite packages that will be available in the docker container
without Dockerfile use this code in windows PowerShell :
docker run --rm -v ${pwd}:/app composer:latest require --dev phpunit/phpunit:^8
create composer container to install phpunit then remove the container.
note: in windows Command %cd% / in windows PowerShell ${pwd} / in linux $PWD
then Create new PHP container with copy all fills include phpuint feamework
docker run -d -p 80:80 --name my-php-apache -v ${pwd}:/var/www/html php:7.4.0-apache

QUESTIONS
Is jenkins-cli downloading
which directory its unable to locate
do i need to run jenkins in background to download jenkins-cli aand
work and How to do it?
and solutions for it
Thank u in advance

CMD ["--help"]
you can try after updating your Dockfile entrypoint as
ENTRYPOINT ["java","-jar","/opt/tmp/jenkin-cli.jar","-noCertificateCheck","-noKeyAuth"]
and also remove following lines:
RUN chmod 644 jenkins-cli.jar
WORKDIR /opt/tmp/jenkins-cli
COPY opt/tmp/jenkins-cli.jar ./jenkins-cli
This looks like a typo error. In your curl command i.e step 19/27, --output is /opt/tmp/jenkin-cli.jar it needs to be /opt/tmp/jenkins-cli.jar.
Error states that it is unable to locate the file /opt/tmp/jenkins-cli.jar because you created the file with name jenkin-cli.jar & not jenkins-cli.jar.
Now the 2nd mistake is you are missing / before opt and moreover,
COPY works from host to container & not within the container. In that case, you don't need to download the CLI to create a container and image.
I am trying to build a docker image using the following docker file.
FROM ubuntu:latest
# Replace shell with bash so we can source files
RUN rm /bin/sh && ln -s /bin/bash /bin/sh
# Update packages

CMD ["node", "-v"]
But I keep getting an error when trying to run it:
docker: Error response from daemon: Container command 'node' not found or does not exist..
I know node is being properly installed because if I rebuild the image by commenting out the CMD line from the docker file
#CMD ["node", "-v"]
And then start a shell session
docker run -it testimage
I can see that all my dependencies are there and return proper results
node -v
v5.10.1
.....
ng -v
angular-cli: 1.0.0-beta.5
node: 5.10.1
os: linux x64
So my question is. Why is the CMD in Dockerfile not able to run these and how can I fix it?
When using the shell to RUN node via nvm, you have sourced the nvm.sh file and it will have a $PATH variable set in it's environment to search for executable files via nvm.
When you run commands via docker run it will only inject a default PATH
docker run <your-ubuntu-image> echo $PATH
docker run <your-ubuntu-image> which node
docker run <your-ubuntu-image> nvm which node
Specifying a CMD with an array execs a binary directly without a shell or a $PATH to lookup.
Provide the full path to your node binary.
CMD ["/bin/node","-v"]
It's better to use the node binary rather than the nvm helper scripts due to the way dockers signal processing works. It might be easier to use the node apt packages in docker rather than nvm.
