I have bash script that performing some Docker commands:
#!/usr/bin/env bash
echo "Create and start database"
cd ../../database
cp -R ../../../scripts/db db/
docker build -t a_database:1 .
docker run --rm --name a_db -e POSTGRES_PASSWORD=docker -d -p 5432:5432 a_database:1
docker network connect --ip 172.23.0.5 a_network a_db
sleep 15
echo "Initialize database"
docker exec a_db /root/db/dev/init_db.sh
echo "Cleanup"
rm -rf db
On mac everything works fine, problem occurs when I try to start this script on windows machine. When I'm running it I receive an error:
OCI runtime exec failed: exec failed: container_linux.go:344: starting container process caused "exec: \"C:/Program Files/Git/root/db/dev/init_db.sh\": stat C:/Program Files/Git/root/db/dev/init_db.sh: no such file or directory": unknown
Directory and script (/root/db/dev/init_db.sh) exist inside docker container. I don't know why it tries to find script on host machine? Also when I perform command:
docker exec a_db /root/db/dev/init_db.sh
directly in command line (on windows) script is executed. Any idea what is wrong and why it's trying to use git ?
I had a similar problem... absolute paths with windows variables fixed mine:
$HOME/docker/...
Thanks to igaul answer I was able to run this on windows machine. There were two problems:
Path to script in docker container. Instead of:
docker exec a_db /root/db/dev/init_db.sh
should be:
docker exec a_db root/db/dev/init_db.sh
Line endings in init_db.sh. On windows machine after pulling repository from bitbucket line ending of init_db.sh was setup to CRLF what caused problem. I've added .gitattribute file to my repo and now init_db.sh file always has LF endings.
It's not a bug in Docker, but the way mingw handles these paths. Here is some more information about that "feature"; http://www.mingw.org/wiki/Posix_path_conversion. Prefixing the path with a double slash (//bin/bash) should prevent this, or you can set MSYS_NO_PATHCONV=1, see How to stop MinGW and MSYS from mangling path names given at the command line

I am trying to open a file inside docker bash (I am using ubuntu terminal btw) using the ff commands:
sudo docker container exec -it rubybox bash
mkdir rubyfiles
cd rubyfiles
touch Dockerfile
And now when I run:
code .
It's suppose to open the file in Visual Studio code but instead I got this error:
bash: code: command not found
Any idea what's the correct command or how to configure this in order to open a file inside docker or terminal after running code .?
You cannot open a GUI app with Docker. You need to share your screen with it.
See: https://medium.com/#SaravSun/running-gui-applications-inside-docker-containers-83d65c0db110
What you could do is to share the local PWD with Docker and work from here:
docker run -d -v $PWD:/t -w /t rubybox
I've wrote a shell script file on mac to deploy some docker application. But when I copy it to Windows10, it seems that it cannot run properly.
The path after "docker exec xx /foo/bar" is always transferred into an absolute path in windows, and leads to an error like: "sh: D:/DevTools/Git/root/start_zk.sh: No such file or directory".
What's more, when executing "docker exec xx /foo/bar" in powershell or git bash, it can run properly. This problem only occurs when I write it into a file, and run it through "sh deploy.sh".
I've tried to add "\" before "/", but it doesn't help. My code is listed below.
echo "deploying zookeepers..."
docker exec ac sh /root/start_zk.sh
Is there any fault in my script? The command "sh /root/start_zk.sh" after "docker exec" should be a parameter for the docker container to execute, but it seems that it is recognized by windows as a command or path. Is there any way to solve this?
So I am running a script that calls:
docker-compose run --rm web sh /data/bin/install_test_db.sh
and it seems to work fine when running it on ubuntu but when I run it on Windows using Git Bash I get this error:
sh: 0: Can't open C:/Program Files/Git/data/bin/install_test_db.sh
It seems to be trying to run the script on my machine and not the actual container from which I am trying to call it from.
Any ideas on why this is happening?
First, try passing a command to your sh shell:
docker-compose run --rm web sh -c "/data/bin/install_test_db.sh"
Or:
docker-compose run --rm web "sh -c /data/bin/install_test_db.sh"
That will avoid your host shell (the git bash) to interpret an absolute path (starting with '/') as one from the Git installation path.
That will keep /data/... as an argument to be passed to the shell executed in the container.
Note: If you are using Docker for Windows (meaning not VirtualBox, but HyperV), you don't need git bash at all.
Try the same command from a regular CMD (with docker.exe in your %PATH%, which Docker for Windows set for you)
vonc#VONCAVN7 C:\Users\vonc
> where docker
C:\Program Files\Docker\Docker\Resources\bin\docker.exe
If you need Linux-like commands from that same CMD session, then yes, add git paths:
set GH=C:\path\to\git
set PATH=%GH%\bin;%GH%\usr\bin;%GH%\mingw64\bin;%PATH%
I run docker in my win10, but use -v params has a error.
docker run --privileged=true -d --name=ubuntu14.04 -v e:/docker/data:/data ubuntu /bin/bash
error:
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: oci runtime error: container_linux.go:262: starting container process caused "exec: \"C:/Program Files/Git/usr/bin/bash\": stat C:/Program Files/Git/usr/bin/bash: no such file or directory".
When I ls this path just like error path pic:
If possible, try the same command in a regular DOS session, instead of a git bash.
That will avoid the git bash session to automatically resolve /bin/bash to C:/Program Files/Git/usr/bin/bash, which won't be known at all by the ubuntu container.
The OP confirms this is working, provided the following options are added:
--attach=STDIN
--privileged=true
winpty docker run -i -t test1 ./bin/sh
Will work on Windows OS.
Add two slashes before bin/sh to turn off GitBash's automatic path conversion.
docker run --privileged=true -d --name=ubuntu14.04 -v e:/docker/data:/data ubuntu //bin/bash
or if you're trying to attach to a running container
docker attach -it ubuntu //bin/bash
Input:
- There is Windows machine with Docker Toolbox installed.
- There is a shell script file baz.sh which calls py2dsc-deb.
Problem: py2dsc-deb is not available on Windows.
As I understand correctly, I can pull some Linux distro image from Docker repository, create a container and then execute shell-script file and it will run py2dsc-deb and do its job.
I have pulled:
debian - stretch-slim - 3ad21 - 3 weeks ago - 55.3MB
Now
How do I run my script using debian, something like: docker exec mycontainer /path/to/test.sh?
Running docker --rm debian:stretch-slim does nothing. Doesn't it suppose to run Debian distro at docker-machine ip?
I have tried to keep the container up using docker run -it debian:stretch-slim /bin/bash, then run the script using docker exec 1ef5b ./build.sh, but getting
$ docker exec 745 ./build.sh
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "exec: \"./build.sh\": stat ./build.sh: no such file or directory"
Does it mean I can't run external script and has to always pass it inside the Docker?
You can execute bash command inside your container by typing
docker exec -ti -u `username` `container_name` bash -c "cd /path/to/ && ./test.sh"
lets say your container name is test_buildbox, you are root and your script stays inside /bin/test.sh You can call this script by typing
docker exec -ti -u root test_buildbox bash -c "cd /bin/ && ./test.sh
Please check if you have correct line endings in your .sh scripts (<LF>) when you built Docker image on Windows.
