I have the following Dockerfile:
FROM sonarqube
RUN wget https://github.com/gabrie-allaigre/sonar-gitlab-plugin/releases/download/4.0.0/sonar-gitlab-plugin-4.0.0.jar
COPY sonar-gitlab-plugin-4.0.0.jar /opt/sonarqube/extensions/plugins/
And I get the following error while copying the file:
Removing intermediate container 63a3ae1d7390
Step 3/3 : COPY sonar-gitlab-plugin-4.0.0.jar /opt/sonarqube/extensions/plugins/
lstat sonar-gitlab-plugin-4.0.0.jar: no such file or directory
How can I copy the file in this case?
You are trying to copy a file located in your container as if it was a local file, so Docker is unable to find it.
Use ADD like this should make it work :
FROM sonarqube
ADD https://github.com/gabrie-allaigre/sonar-gitlab-plugin/releases/download/4.0.0/sonar-gitlab-plugin-4.0.0.jar /opt/sonarqube/extensions/plugins/
it's more "dockerlike"
You're running wget inside the container, but then trying to COPY it from the host machine to the container. To copy from one container location to another simply use cp:
RUN wget https://github.com/gabrie-allaigre/sonar-gitlab-plugin/releases/download/4.0.0/sonar-gitlab-plugin-4.0.0.jar \
&& cp sonar-gitlab-plugin-4.0.0.jar /opt/sonarqube/extensions/plugins/
Better yet, just use wget -O to save the file in the desired location from the get go.
RUN wget -o /opt/sonarqube/extensions/plugins/ \
https://github.com/gabrie-allaigre/sonar-gitlab-plugin/releases/download/4.0.0/sonar-gitlab-plugin-4.0.0.jar
COPY command copies file from the host to the container.
For any command you want to run inside the container you need RUN:
RUN wget https://github.com/gabrie-allaigre/sonar-gitlab-plugin/releases/download/4.0.0/sonar-gitlab-plugin-4.0.0.jar \
&& cp sonar-gitlab-plugin-4.0.0.jar /opt/sonarqube/extensions/plugins/

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
FROM openjdk:11-jre
ARG uaa_yml_name=local.yml
ENV UAA_CONFIG_PATH /uaa
ENV CATALINA_HOME /tomcat
ADD run.sh /tmp/
ADD conf/$uaa_yml_name /uaa/uaa.yml

RUN rm -rf /tomcat/webapps/ROOT.war
EXPOSE 8080
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've been trying to get this running for many MANY hours. I've been scouting docker docs, github repos and other stuff but I can't get it working for some reason.
My dockerfile:
FROM mattrayner/lamp:latest-1804
WORKDIR /app
RUN wget -O /tmp/lwt.zip http://downloads.sourceforge.net/project/lwt/lwt_v_1_6_3.zip && \
yes A | unzip /tmp/lwt.zip &&\
rm /tmp/lwt.zip &&\
mv connect_xampp.inc.php connect.inc.php
EXPOSE 80
CMD ["/run.sh"]
It build normally without any errors but when I run the image nothing appears in the /app directory and I get just a basic Welcome to LAMP view on my browser.
Though,
If I do docker run -p "80:80" -it -v ${PWD}/app:/app mattrayner/lamp:latest-1804 /bin/bash, cd /app, copy and paste
wget -O /tmp/lwt.zip http://downloads.sourceforge.net/project/lwt/lwt_v_1_6_3.zip && \
yes A | unzip /tmp/lwt.zip &&\
rm /tmp/lwt.zip &&\
mv connect_xampp.inc.php connect.inc.php
it still doesn't work BUT if I exit and run the same docker run command it works.
Docker LAMP instructions also state to do exactly as I have done:
FROM mattrayner/lamp:latest-1804
# Your custom commands
CMD ["/run.sh"]
As I followed these instructions I thought that everything would work nicely.
What's the catch here? It has something to do with the intermediate containers probably but I can't comprehend it (I'm not a devops or developer by trade, just a hobbyist).
That happens because you're doing this:
Download a file (wget ...) in your /app dir in your docker image.
After that, you're overwritting this /app dir when you mount volume, with content of your $PWD/app.
If you are installing something doing docker build in some dirs, don't mount into the same path.
If you need something in the same path, you can mount some concrete files, but not the whole dir, or it will override what you had in your docker image when container is created.
You can do wget somewhere else or download it into your ${PWD}/app and then mount it.
So, I have built a beat with mage GenerateCustomBeat and it runs okay, except, now I'm trying to cotainerize it. When I run the image I built, it complains that no customBeat.yml was found.
I have secured that the file exists in the folder by adding a line RUN ls . at the end of my Dockerfile.
The beat name is coletorbeat, so this name appears multiple times inside the Dockerfile.
Upon executing sudo docker run coletorbeat I have the following error message:
Exiting: error loading config file: stat coletorbeat.yml: no such file or directory
If there was a way to specify the coletorbeat.yml file location when I execute the beat, in CMD I think I would solve it, but I have not found how to do so yet.
I'll post the Dockerfile below. I know the code inside the beater folder works fine. I'm guessing I'm making some mistake on the containerization.
Dockerfile:

RUN cd /coletorbeat && ./coletorbeat test config -c /coletorbeat/coletorbeat.yml && ls .
CMD ./coletorbeat/coletorbeat -E 'coletorbeat.ip=${ip}'
You are adding the yml file into the /etc dir
COPY /coletorbeat/coletorbeat.yml /etc/coletorbeat/coletorbeat.yml
But then running commands on /coletorbeat without using etc.
On CMD line in the Dockerfile, I added the command cd /mybeatfolder and it worked. Libbeat searches the current folder for the config file as default, so moving to the right directory before executing my beat solved it.
Docker COPY is not copying over the bash script
FROM alpine:latest
#Install Go and Tini - These remain.
RUN apk add --no-cache go build-base gcc go
RUN apk add --no-cache --update ca-certificates redis git && update-ca-certificates
# Set Env Variables for Go and add Go to Path.
ENV GOPATH /go
ENV PATH $GOPATH/bin:/usr/local/go/bin:$PATH
RUN go get github.com/rakyll/hey
RUN echo GOLANG VERSION `go version`
COPY ./bench.sh /root/bench.sh
RUN chmod +x /root/bench.sh
ENTRYPOINT /root/bench.sh
Here is the script -
#!/bin/bash
set -e;
echo "entered";
hey;
I try running the above Dockerfile with
$ docker build -t test-bench .
$ docker run -it test-bench
But I get the error
/bin/sh: /root/bench.sh: not found
The file does exist -
$ docker run --rm -it test-bench sh
/ # ls
bin dev etc go home lib media mnt opt proc root run sbin srv sys tmp usr var
/ # cd root
~ # ls
bench.sh
~ #
Is your docker build successful. When I tried to simulate this, found the following error
---> Running in 96468658cebd
go: missing Git command. See https://golang.org/s/gogetcmd
package github.com/rakyll/hey: exec: "git": executable file not found in $PATH
The command '/bin/sh -c go get github.com/rakyll/hey' returned a non-zero code: 1
Try installing git using Dockerfile RUN apk add --no-cache go build-base gcc go git and run again.
The COPY operation here seems to be correct. Make sure it is present in the directory from where docker build is executed.
Okay, the script is using /bin/bash the bash binary is not available in the alpine image. Either it has to be installed or a /bin/sh shell should be used
There is the following code In my Dockerfile :
ENV GOVERS 073fc578434b
RUN cd /usr/local && curl -O http://go.googlecode.com/archive/$GOVERS.zip
RUN cd /usr/local && unzip -q $GOVERS.zip
the above code downloads the zip file to the /usr/local directory and all is ok. But now i do not want to download the zip file, I want to get the zip file from my local PC to the /usr/local at the docker container.
Let say the zip file is named test.zip and is located in the same directory as your Dockerfile, then you can make use of the COPY instruction in your dockerfile. You will then have:
COPY test.zip /usr/local/
RUN cd /usr/local && unzip -q test.zip
Furthermore you can use the ADD instruction instead of COPY to also uncompress the zip file and you won't need to RUN the unzip command:
ADD test.zip /usr/local/
Another approach that I am starting to like is using volumes and runtime commands. I don't like to have to rebuild the image if I change something incidental.
So I create a volume in the docker file to transfer stuff back and forth:
In Docker file:
RUN mkdir -p /someplace/dropbox
....
CMD ..... ; $POST_START ; tail -f /var/log/messages
on host:
mkdir /dropbox && cp ~/Downloads/fap.zip /dropbox \
docker run -v /dropbox:/someplace/dropbox \
-e POST_START="cp /someplace/dropbox/fap.zip /someplace-else; cd /someplace-else;unzip fap.zip" ..... <image>
