I'm trying to dockerize cassandra by following below steps.
Docker file ->
FROM oraclelinux:7.3
COPY apache-cassandra-2.2.8-bin.tar.gz /opt
RUN cd /opt && tar -xvzf apache-cassandra-2.2.8-bin.tar.gz
RUN cd /opt && ln -s apache-cassandra-2.2.8 cassandra
RUN cd /opt/cassandra && mkdir data && mkdir commitlog && mkdir saved_caches
COPY cassandra.yaml /opt/cassandra/conf
COPY cassandra-topology.properties /opt/cassandra/conf
RUN chmod +x /opt/cassandra/bin/cassandra
ENV CASSANDRA_CONFIG /opt/cassandra/conf
ENV CASSANDRA_HOME /opt/cassandra
RUN /opt/cassandra/bin/cassandra
ENTRYPOINT ["/opt/cassandra/bin/cassandra"]
EXPOSE 7000 7001 7199 9160
When I build cassandra docker using
docker build -t my_cassandra .
throws below error message
Step 19/21 : RUN /opt/cassandra/bin/cassandra
---> Running in 36bd332c523a
cat: /etc/ld.so.conf.d/*.conf: No such file or directory
When I build cassandra docker using
docker run -it my_cassandra bin/bash
it throws same error message
cat: /etc/ld.so.conf.d/*.conf: No such file or directory
If I remove the ENTRYPOINT line or hash it out, docker builds and runs fine but cassandra doesn't run as part of docker run command. I have to logon to the container and manually start with ./cassandra
Is there a way I could start cassandra as part of docker run command here?
From your example above, it doesn't look like ENTRYPOINT is the problem here. You should not run Cassandra as part of the Docker build.
Step 19/21 : RUN /opt/cassandra/bin/cassandra
---> Running in 36bd332c523a
cat: /etc/ld.so.conf.d/*.conf: No such file or directory
Remove RUN /opt/cassandra/bin/cassandra.
Take a look at the official Cassandra Docker Image on Docker Hub.
link: Official Dockerfile
link: Docker Hub - Cassandra
It boils down to the upstream image you use. /opt/cassandra/bin/cassandra seems to be a shell script which executes which ldconfig at some point. If which is missing from your image, you will see such error

I have built a local uaa docker image and tried to run in local.
But I am getting this error when I am trying to start the docker image.
I built the docker image via this below command and the build is successful too.
docker build -t uaa-local --build-arg uaa_yml_name=local.yml .
when I am trying to run the local uaa docker image, I am getting this below error. What I am doing wrong
Content of DockerFile

CMD ["/tmp/run.sh"]
On further investigation I think it is looking for run.sh file in the /tmp/ folder which is added on line 5 in Dockerfile..but when I checked for the file in /tmp/ folder it is not there..Is it because of that?And how to resolve that? I already have the run.sh in my current folder.
I'm fuzzing php inside docker container. Before fuzzing process start, it download and build php from source, then run fuzzing job. I'm using -d to run container in background.
sudo docker run --name=fuzzphp -d -v ~/crashfile:/fuzzer/script/fuzzing/ --privileged --cap-add=SYS_PTRACE fuzzphp /bin/bash -c "./tool/autophp.sh"
Here is the autophp.sh script doing build and run php.
./script/build/buildphp.sh
./script/fuzzing/runphp.sh
Here is my Dockerfile
FROM ubuntu:16.04
#install required package
RUN mkdir -p /fuzzer
WORKDIR /fuzzer
COPY . /fuzzer
ENV PATH "/fuzzer/clang+llvm/bin:$PATH"
ENV LD_LIBRARY_PATH "/fuzzer/clang+llvm/lib:$LD_LIBRARY_PATH"
RUN ["chmod" "777" "-R" "script/"]
RUN tool/install_fuzzer.sh
The problem is after I run autophp.sh by checking sudo docker logs fuzzphp only build script success, and runphp.sh return an error
chmod: cannot access '/script/fuzzing/buildphp.sh': No such file or directory
./tool/autophp.sh: line 5: ./script/fuzzing/runphp.sh: No such file or directory
I can confirm /script/fuzzing/runphp.sh file is exist on host but I don't have idea only buildphp is executed, but not runphp. What's wrong here?
I made a webapp in Java and I would like to test the site locally using Docker.
The war file I created works perfectly but to be read correctly it must be inserted inside this path:
/tomcat/webapps/ROOT/
For these reasons I decided to use this form:
https://hub.docker.com/_/tomcat
In particular I decided to use this Dockerfile:
https://github.com/docker-library/tomcat/blob/ec2d88f0a3b34292c1693e90bdf786e2545a157e/9.0/jre11-slim/Dockerfile
I added this code towards the end:
...
EXPOSE 8080
CMD ["cd /usr/local/tomcat/webapps/"]
CMD ["mv ROOT ROOT.old"]
CMD ["mkdir ROOT"]
COPY ./esercitazione.1.maven/ /usr/local/tomcat/webapps/ROOT/
CMD ["catalina.sh", "run"]
I used this code at the Windows 10 prompt:
D:
cd "D:\DATI\Docker-Tomcat-Win10"
docker build -t tomcat-9-java-11:v2.0 .
docker run -it --rm --name tomcat-9-java-11-container -p 8888:8080 tomcat-9-java-11:v2.0
When I enter this link on the browser:
http://192.168.99.103:8888/
I see this:
https://prnt.sc/n2vti1
I'm a beginner with both Docker and Tomcat and I need a little help.
Inside this path I put my unzipped .war file:
D:\DATI\Docker-Tomcat-Win10\esercitazione.1.maven
Thank you

First of all thank you for your help!
I deleted all the containers and all the images on Docker and used your Dockerfile (I only changed the name of the folder containing the .war files to be tested).
FROM tomcat:9-jre8
ENV JAVA_OPTS="-Xms512m -Xmx1024m -XX:MaxPermSize=256m -XX:MaxMetaspaceSize=128m"
WORKDIR /usr/local/tomcat/webapps/
RUN rm -rf /usr/local/tomcat/webapps/*
COPY ./webapps/*.war /usr/local/tomcat/webapps
EXPOSE 8080
CMD ["catalina.sh", "run"]
I placed the .war file at this address:
D:\DATI\Docker-Tomcat-Win10\webapps\esercitazione.1.maven.war
I opened the Windows prompt and I typed:
D:
cd "D:\DATI\Docker-Tomcat-Win10"
docker build -t tomcat:v1.0 .
docker run -it --rm --name tomcat-container -p 8888:8080 tomcat:v1.0
I entered this URL in the browser:
http://192.168.99.103:8888/esercitazione.1.maven/
then this other:
http://192.168.99.103:8888/
Unfortunately none of them went well.
The only mistake I encountered when creating the image is this:
"SECURITY WARNING: You are building to Docker image from Windows against a non-Windows Docker host. Files and directories added to build context will have '-rwxr-xr-x' permissions. It is recommended to double check and reset permissions for sensitive files and directories."

Is this a problem without a solution?
The biggest problem I see here is that you use CMD instead RUN in your dockerfile. CMD is to define a command that will be run when container is ran. With the Dockerfile you have now, only the last one is executed when you start your container and all of those mkdirs, moves, etc. are never executed. As said, you need to use RUN keywords to indicate command that build process should execute and commit as image layer. You probably also do not need the catalina.sh CMD as it might come from the image you base on, but you need to check it on doc page for the base image or take a peek to it's Dockerfile or use docker history imagename To see the layers and commands used to create them.
I took a deeper look into this and the base image you use. In addition to the CMD's your problem is that you change the workdir by running cd commands. catalina.sh exists in $CATALINA_HOME dir, which then is marked as workdir in base image. When you change the active directory by executing cd it breaks the image runtime.
I'd suggest you try with following dockerfile:
FROM tomcat:9-jre11-slim
RUN mv webapps/ROOT webapps/ROOT.old && mkdir webapps/ROOT
COPY ./esercitazione.1.maven/ webapps/ROOT/
No need to use EXPOSE and CMD as they are defined in base image. also, base image defines WORKDIR to $CATALINA_HOME and that's where you will be when executing any following commands (treat WORKDIR as cd but in docker style).
Hope that helps.
First you need to compile your Code to a war file then you can use below Dockerfile
FROM tomcat:9-jre8
ENV JAVA_OPTS="-Xms512m -Xmx1024m -XX:MaxPermSize=256m -XX:MaxMetaspaceSize=128m"
WORKDIR /usr/local/tomcat/webapps/
RUN rm -rf /usr/local/tomcat/webapps/*
COPY ./esercitazione.1.maven/*.war /usr/local/tomcat/webapps
EXPOSE 8080
CMD ["catalina.sh", "run"]
I am creating one docker image name with soaphonda.
the code of docker file is below

My image creation is getiing successfull. I want that once the image creation is done it should retag and push in the docker hub. For that i have created the script which is below;
docker tag soaphonda ankiksri/soaphonda
docker push ankiksri/soaphonda
docker login
docker run -d -p 8089:8089 --name demo ankiksri/soaphonda
containerid=`docker ps -aqf "name=demo"`
echo $containerid
docker exec -it $containerid bash -c 'cd ../SoapUI-5.3.0;sh /opt/SoapUI-5.3.0/bin/mockservicerunner.sh "/opt/SoapUI-5.3.0/Honda-soapui-project.xml"'
Please help me how i can call the second script from docker file and the exit command is not working in docker file.
What you have to understand here is what you are specifying within the Dockerfile are the commands that gets executed when you build and run a Docker container from the image you have created using your Dockerfile.
So Docker image tag, push running should all done after you have built the Docker image from the Dockerfile. It cannot be done within the Dockerfile itself.
To achieve this kind of a thing you would have to use a build tool like Maven (an example) and automate the process of tagging, pushing the image. Also by looking at your image, I don't see any nessactiy to keep on tagging and pushing the image unless you are continuously updating the image. Also there is no point of using three FROM commands as it will unnecessarily make your Docker image size huge.
I am building Scigraph database on my local machine and trying to move this entire folder to docker and run it, when I run the shell script on my local machine it runs without error when I add the same folder inside docker and try to run it fails
Am I doing this right way, here's my DOckerfile
FROM goyalzz/ubuntu-java-8-maven-docker-image
ADD ./SciGraph /usr/share/SciGraph
WORKDIR /usr/share/SciGraph/SciGraph-services
RUN pwd
EXPOSE 9000
CMD ['./run.sh']
when I try to run it I'm getting this error
docker run -p9005:9000 test
/bin/sh: 1: [./run.sh]: not found
if I run it using below command it works
docker run -p9005:9000 test -c "cd /usr/share/SciGraph/SciGraph-services && sh run.sh"
as I already marked the directory as WORKDIR and running the script inside docker using CMD it throws error
For scigraph as provided in their ReadMe, you can to run mvn install before you run their services. You can set your shell to bash and use a docker compose to run the docker image as shown below
Dockerfile
FROM goyalzz/ubuntu-java-8-maven-docker-image
ADD ./SciGraph /usr/share/SciGraph
SHELL ["/bin/bash", "-c"]
WORKDIR /usr/share/SciGraph
RUN mvn -DskipTests -DskipITs -Dlicense.skip=true install
RUN cd /usr/share/SciGraph/SciGraph-services && chmod a+x run.sh
EXPOSE 9000
build the scigraph docker image by running
docker build . -t scigraph_test
docker-compose.yml
version: '2'
services:
scigraph-server:
image: scigraph_test
working_dir: /usr/share/SciGraph/SciGraph-services
command: bash run.sh
ports:
- 9000:9000
give / after SciGraph-services and change it to "sh run.sh" ................ and look into run.sh file permissions also
It is likely that your run.sh doesn't have the #!/bin/bash header, so it cannot be executed only by running ./run.sh. Nevertheless, always prefer to run scripts as /bin/bash foo.sh or /bin/sh foo.sh when in docker, especially because you don't know what changes files have been sourced in images downloaded from public repositories.
So, your CMD statement would be:
CMD /bin/bash -c "/bin/bash run.sh"
You have to add the shell and the executable to the CMD array ...
CMD ["/bin/sh", "./run.sh"]
