Docker ERROR：从Win10运行时找不到容器命令或不存在容器命令

Question

This is driving me crazy...

I have Win10 and I have installed the Docker Toolbox with

Docker=1.10.2 
Compose=1.6.0 
VirtualBox=5.0.14

I have successfully launched the LAMP in Linux [Amazon linux] but when I try to do the same the terminal responds with "ERROR: Container command not found or does not exist" As I understand, there is something wrong with the way Windows interpreter the CMD syntax.

I have tried

 - CMD ["/run.sh"]
 - ENTRYPOINT ["/run.sh"]     
 - CMD /run.sh
 - CMD '/run.sh'
 - CMD run.sh
 - CMD "/run.sh"

but nothing seems to work.

Note: When I run CMD /run.sh the error does not appear but the container exits immediately.

Note2: I have exactly the same problem when trying to setup the LAMP with Docker-Machine on AWS

I have this DockerfileLamp :

CMD /run.sh

and the run.sh :

#!/bin/bash

sed -ri -e "s/^upload_max_filesize.*/upload_max_filesize = ${PHP_UPLOAD_MAX_FILESIZE}/" \
    -e "s/^post_max_size.*/post_max_size = ${PHP_POST_MAX_SIZE}/" /etc/php5/apache2/php.ini
if [[ ! -d $VOLUME_HOME/mysql ]]; then
    echo "=> An empty or uninitialized MySQL volume is detected in $VOLUME_HOME"
    echo "=> Installing MySQL ..."
    mysql_install_db > /dev/null 2>&1
    echo "=> Done!"  
    /setup_MySQL.sh
else
    echo "=> Using an existing volume of MySQL"
fi

exec supervisord -n

and the docker-compose.yml :

lamp: # apache + mysql/php
  build: .
  dockerfile: DockerfileLamp
  ports:
    - "8181:80"   # open apache to public
    - "3333:3306" # open mysql to public 
    - "2222:22"   # open SSH to public

Answer 1

Docker is process centric, in other words your containers dies when your CMD script dies. At the end of your script run ...

tail -f logfile (where logfile is some logfile you are interested in)

This will

1 - stop your container exiting 2 - allow you to do

docker logs -f containerName

To help u debug

3 - allow you to enter into the container with

docker exec -it bash containerName 

Then u can run the command that you think is failing inside the container and try n sort this out

Whilst this doesn't directly answer your question it should give u sufficient weaponry to attack this issue

Answer 2

For another project I tried to get to work on Windows with Docker Machine I ran into the same ambiguous error message of docker-compose Container command not found or does not exist .

Your comment about line endings triggered me to try dos2unix ./*/*.sh within git-bash (multiple scripts, in subfolders), which fixed the issue for me.

My suspicion is that git clone saves the files with DOS line endings, which results in incorrect syntax for the top line !#/bin/bash .

$ docker-compose -v
docker-compose version 1.6.2, build e80fc83

$ docker version
Client:
 Version:      1.10.3
 API version:  1.22
 Go version:   go1.5.3
 Git commit:   20f81dd
 Built:        Thu Mar 10 21:49:11 2016
 OS/Arch:      windows/amd64

Server:

Answer 3

I solved it by simplifying the file. I commented out all the controls because whatever I tried it would keep throwing Syntax Errors

#!/bin/bash

VOLUME_HOME="/var/lib/mysql"

sed -ri -e "s/^upload_max_filesize.*/upload_max_filesize = ${PHP_UPLOAD_MAX_FILESIZE}/" \
    -e "s/^post_max_size.*/post_max_size = ${PHP_POST_MAX_SIZE}/" /etc/php5/apache2/php.ini

#if [[ ! -d $VOLUME_HOME/mysql ]]; then
    echo "=> An empty or uninitialized MySQL volume is detected in $VOLUME_HOME"
    echo "=> Installing MySQL ..."
    mysql_install_db > /dev/null 2>&1
    echo "=> Done!"
    /setup_MySQL.sh
#else
#    echo "=> Using an existing volume of MySQL"
#fi

exec supervisord -n

It works for my case so I am not going to investigate further. Cheers!

EDITED

The above solution was not so complete. It worked because I was making changes from INSIDE the container.

The permanent solution goes like this : I migrated the run.sh file to a private Gist . [It does not need to be private but ok] I think the problem is that when I try to build the Dockerfile from Windows machine [either locally or on a cloud provider] it messes up the syntax , EOF , line breaks and whatnot. So I broke out of it by ADDing the gist url

ADD http://gist_url/run.sh /run.sh

Note1: You must use the raw file URL otherwise you are going to get the complete HTML.

Note2: The private gist is not protected.You don't need authentication to fetch the URL.
