echo "Hi There - Welcome to Docker POC">C:/Users/abc/xyz/POC/poc.html
The above echo command works from windows powershell but the same does not work when it is included in a Dockerfile as given below.
RUN echo "Hi There - Welcome to Docker POC">C:/Users/abc/xyz/POC/poc.html
The Error is : System cannot find the path specified.
Pls help.
This is because the path you give at the end of the RUN command in the Dockerfile is into the container.
You probably want to run the command into a docker container. If so, please run:
docker run --rm -v C:/Users/abc/xyz/POC/:/POC busybox sh -c 'echo "Hi There - Welcome to Docker POC" > /POC/poc.html'
And you will see 'poc.html' file in 'C:/Users/abc/xyz/POC/'.
Tell if I misunderstood your request.

This is my 3rd day of tear-your-hair-out since the weekend and I just cannot get ENTRYPOINT to work via gitlab runner 13.3.1, this for something that previously worked with a simple ENTRYPOINT ["/bin/bash"] but that was using local docker desktop and using docker run followed by docker exec commands which worked like a synch. Essentially, at the end of it all I previously got a WAR file built.
Currently I build my container in gitlab runner 13.3.1 and push to s3 bucket and then use the IMAGE:localhost:500/my-recently-builtcontainer and then try and do whatever it is I want with the container but I cannot even get ENTRYPOINT to work, in it's exec form or in shell form - atleast in the shell form I get to see something. In the exec form it just gave "OCI runtime create failed" opaque errors so I shifted to the shell form just to see where I could get to.
I keep getting
sh: 1: sh: echo HOME=/home/nonroot-user params=#$ pwd=/ whoami=nonroot-user script=sh ENTRYPOINT reached which_sh=/bin/sh which_bash=/bin/bash PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin; ls -alrth /bin/bash; ls -alrth /bin/sh; /usr/local/bin/entrypoint.sh ;: not found
In my Dockerfile I distinctly have
COPY entrypoint.sh /usr/local/bin/entrypoint.sh
RUN bash -c "ls -larth /usr/local/bin/entrypoint.sh"
ENTRYPOINT "echo HOME=${HOME} params=#$ pwd=`pwd` whoami=`whoami` script=${0} ENTRYPOINT reached which_sh=`which sh` which_bash=`which bash` PATH=${PATH}; ls -alrth `which bash`; ls -alrth `which sh`; /usr/local/bin/lse-entrypoint.sh ;"
The output after I build the container in gitlab is - and I made sure anyone has rights to see this file and use it - just so that I can proceed with my work
-rwxrwxrwx 1 root root 512 Apr 11 17:40 /usr/local/bin/entrypoint.sh
So, I know it is there and all the chmod flags indicate anybody can look at it - so I am so perplexed why it is saying NOT FOUND
/usr/local/bin/entrypoint.sh ;: not found
entrypoint.sh is ...
#!/bin/sh
export PATH=$PATH:/usr/local/bin/
clear
echo Script is $0
echo numOfArgs is $#
echo paramtrsPassd is $#
echo whoami is `whoami`
bash --version
echo "About to exec ....."
exec "$#"
It does not even reach inside this entrypoint.sh file.
I've a weird error, I'm trying to run a python script in ECS, the dockerfile is pretty basic:
FROM python:3.8
COPY . /
RUN pip install -r requirements.txt
CMD ["python", "./get_historical_data.py"]
building this in my local machine works perfect,
docker run --network=host historical-price
I uploaded this image to ECR and run on ECS, a basic config, just set container name, pointing the Image to my ECR repo and set some environment variables...when I run this I get
Status reason CannotStartContainerError: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "python": executable file not found in $PATH: unknown
but (really weird) if I enter in the EC2 server and run the container manually
docker run -it -e TICKER='SOL/USDT' -e EXCHANGE='BINANCE' -e DB_HOST='xxx' -e DB_NAME='xxx' -e DB_PASSWORD='xxx' -e DB_PORT='xxx' -e DB_USER='xxx' xxx.dkr.ecr.ap-southeast-2.amazonaws.com/xxx:latest /bin/bash
I can see this running ok...
I've tried several dockerfiles, using
CMD python ./get_historical_data.py
or using python3 command instead of python
also I tried to skip the CMD command in the Dockerfile and add this in the ECS task definition
nothing work...
I really don't know what can be happen here because the last week I ran a similar task and this worked perfectly, hope you can help me
thank you, please let me know if you need more details

I am running the above command from container in Buildspec as well as tested in ec2 instance , Command is failing with error: sh: infacmd.sh: command not found
But When i tried only command sshpass -p "xxx" ssh -t -t abc#usllpz107.net.com and executed other command manually in ec2 then command is working.
Make sure the file exists at the path.
Make sure you have access to the file.
Make sure the file is executable or change the command to
; /bin/bash infacmd.sh ...
I am trying to run a docker image (E.g: webwhatsapi) over Selenium network.
I followed below commands:
docker network create selenium
docker run -d -p 4444:4444 -p 5900:5900 --name firefox --network selenium -v /dev/shm:/dev/shm selenium/standalone-firefox-debug
docker build -t webwhatsapi .
docker run --network selenium -it -e SELENIUM='http://firefox:4444/wd/hub' -v $(pwd):/app webwhatsapi /bin/bash -c "pip install ./;pip list;python sample/remote.py"
On AWS, I have following configuration in security group.
I am trying to open the http://{public ip}:4444 in firefox browser. It shows error. (This site can't be reached). I think, I should change my last command in a way which makes it work in browser url.
Last command:
docker run --network selenium -it -e SELENIUM='http://firefox:4444/wd/hub' -v $(pwd):/app webwhatsapi /bin/bash -c "pip install ./;pip list;python sample/remote.py"
Please let me know, where am I going wrong ?
I'm trying to execute lein run in a Clojure Docker image out of a mounted folder that is not /, but when I try to cd into a folder, Docker complains with unable to locate cd:
docker run -v /root/chortles:/test -i jphackworth/docker-clojure cd /test && lein run
=> Unable to locate cd
How do I instruct Leiningen to run in a different folder, or tell Docker to change the directory prior to running my command?
You can use -w param for docker run. This parameter is useful for specifying working directory within container.
docker run -w /test -v /root/chortles:/test -i jphackworth/docker-clojure lein run
The best bet is to add a shell script to the docker image and call that.
Have a script called, say lein-wrapper.sh, install in in /usr/local/bin. The script should sort out the environment for leiningen and then call it. Something like this:
#!/bin/sh
export PATH=${LEININGEN_INSTALL}:${PATH}
cd /test
lein $#
You can set
ENTRYPOINT["/usr/local/bin/lein-wrapper.sh"]
In your Dockerfile
And invoke it as:
# Will call /usr/local/bin/lein-wrapper.sh run
# which will call lein run
docker run -v /root/chortles:/test -i jphackworth/docker-clojure run
# or run lein deps...
docker run -v /root/chortles:/test -i jphackworth/docker-clojure deps
cd is a bash builtin, not a command. You can use bash -c 'cd /test && lein run'. Better yet, do as #Jiri states and use the -w parameter to set the working directory of the container, then just use lein run to start your app.
