I'm new to dockerfile and I have a hard time running a simple check command present in an image.
When I run a container with this image, I'm seeing this behavior from the shell (/bin/sh):
$ /bin/bash -c foamVersion
/bin/bash: foamVersion: command not found
$ /bin/bash
nextfoam#3ab61c950023:/home$ foamVersion
OpenFOAM-6
I'm running it from /bin/sh because this image seems to use it by default (Ubuntu 18).
My goal is to do get foamVersion result. Here's the dockerfile:
FROM nextfoam/baram6:latest
SHELL ["/bin/bash", "-c"]
RUN foamVersion
On host (Ubuntu 21.10), I run:
docker build -t mybaram:latest .

foamVersion is a function
foamVersion ()

cd $WM_PROJECT_DIR;

Any idea how to get foamVersion working from build process in dockerfile?

Hi I am creating an image on docker and below are the commands on Dockerfile
FROM node
WORKDIR /app
COPY . /app
RUN npm install
EXPOSE 80
CMD ["node", "server.js"]
When I run the command Docker build . it gives below response

Can some please guide
I was expecting the image to be built.
I was facing the same problem in a CI/CD context and it was related to the /var/lib/docker directory.
So you can try these steps (doing so you will temporary loose all your Docker layers and images in your host but can revert the operation if not ok)
Stop your docker service
sudo mv /var/lib/docker /var/lib/_docker
restart the Docker service (if needed, sudo mkdir /var/lib/docker)

I'm learning Docker and I'm trying to create the most simple and light image as possible. That's what I did.
helloworld directory:
$ ls
Dockerfile helloworld.c
helloworld.c
#include <stdio.h>
int main() {
printf("Hello world!\n");
return 0;
}
Dockerfile
FROM scratch
COPY helloworld /
CMD ["/helloworld"]
I compiled the .c file:
$ gcc -o helloworld helloworld.c
$ ./helloworld
Hello world!
Then I created the image:
$ docker build --tag helloworld .

Then when I run the container I get the error exec /helloworld: no such file or directory:

What am I doing wrong? Should I compiled the helloworld in a different mode?
You need to compile at docker build time, e.g.:
FROM ubuntu
RUN apt-get update -y && apt-get install gcc -y
COPY helloworld.c .
RUN gcc -o helloworld helloworld.c
ENTRYPOINT ["./helloworld"]
$ docker build -t helloworld .
$ docker run helloworld
Hello world!
I have docker image which already have keys saved.I want to get docker container which will have ssh keys loaded when i run it. I went over few stackoverflow questions where its suggested to use as below which didnt help
RUN eval $(ssh-agent -s) && ssh-add /root/.ssh/ok
My Dockerfile look like
FROM cmf
RUN eval $(ssh-agent -s) && ssh-add /root/.ssh/ok
when i created docker image and ran it like , i dont see keys loaded
docker run -it intro_to_docker2 /bin/bash
root#17a094f42efb:/# ssh-add -l
Could not open a connection to your authentication agent.
root#17a094f42efb:/#
Below is build
% docker build --no-cache -t intro_to_docker2 .

This question already has answers here:
Why is docker build not showing any output from commands?
(6 answers)
Closed 11 months ago.
The answers here don't seem to work. The answer here also doesn't work. I suspect something has changed about Docker's build engine since then.
My Dockerfile:
FROM node:16.14.2-alpine
WORKDIR /usr/src/app
COPY package.json yarn.lock ./
RUN yarn
COPY dist .
EXPOSE $SEEDSERV_PORT
RUN pwd
RUN echo "output"
RUN ls -alh
RUN contents="$(ls -1 /usr/src/app)" && echo $contents
# CMD ["node","server.js"]
ENTRYPOINT ["tail", "-f", "/dev/null"]
Which gives this output from build:
✗ docker build --progress auto --build-arg SEEDSERV_PORT=9999 -f build/api/Dockerfile .

Adding --progress plain gives slightly different output but not what I'm looking for, e.g.:
#11 [7/9] RUN echo "output"
#11 sha256:634e07d201926b0f70289515fcf4a7303cac3658aeddebfa9552fc3054ed4ace
#11 CACHED
How can I get a directory listing during build in 20.10.3? I can exec into the running container but that's a lot more work.
If your build is cached, there's no output from the run to show. You need to include --no-cache to run the command again for any output to display, and also include --progress plain to output to the console.
