I am trying to build Pyodide from source on Windows. In their documentation they recommend using Docker. From the documentation:
1 Install Docker
2 From a git checkout of Pyodide, run ./run_docker or ./run_docker --pre-built
3 Run make to build.
I don't understand how to run ./run_docker?
I don't even know exactly what the file is. Is it a shell script?
Combining your question, "How do I run a script file in Windows?", with the information provided (you want to run a file called run_docker from the Pyodide project) you should get started by installing the Windows Subsystem for Linux version 2 (WSL). After you install WSL, you will need to open a command prompt, run bash to enter the Ubuntu linux distribution. From here you should follow the steps for building on Linux. When you run into a problem you can search the internet for solutions related to "Linux" or "Ubuntu".

I'm trying to use AWS CLI to access CodeCommit. And it's sort of working. I am able to use the aws command in the Windows command prompt. However, when I try to access it using the Git Bash shell, it says
"bash: aws: command not found."
Additionally, when I try to do do a git clone in the Windows command promt, trying to access CodeCommit, it tries to use aws using the credentials helper, which also results in "aws: command not found."
I followed the instructions in the AWS documentation, which suggests some directories to add to the PATH:
https://docs.aws.amazon.com/cli/latest/userguide/awscli-install-windows.html#awscli-install-windows-path
Here's what my PATH variable looks like:
C:\Users\ddrayton\AppData\Local\Programs\Python\Python36\Scripts\;C:\Users\ddrayton\AppData\Local\Programs\Python\Python36\;C:\Windows\System32;;C:\Program
Files\Docker
Toolbox;C:\Users\ddrayton\MyCurl;%USERPROFILE%\AppData\Local\Programs\Python\Python36\Scripts;C:\Program
Files\Amazon\AWSCLI;C:\Program Files
(x86)\Amazon\AWSCLI;C:\Users\ddrayton\AppData\Local\Programs\Python\Python36;C:\Users\ddrayton\AppData\Local\Programs\Python\Python36\Scripts
But I'm not sure if it's a PATH problem, since the Windows command prompt has no problem accessing the "aws" command.
Any ideas?
Fixed this by simply installing the AWS CLI again but this time using Git Bash instead of the Windows command prompt.
pip install awscli
If anyone could provide some insight as to why this was necessary, it would be appreciated.
In my case, I think a recent-to-me update to the AWS CLI changed what's run to being aws.cmd (full path C:\Program Files\Amazon\AWSCLI\bin\aws.cmd)
Git Bash needs the extension aws.cmd to make it work.
In Bash, you could try typing aws.cmd vs aws. If the former works, but not the latter, you can do alias aws='aws.cmd' in your bash startup script. I don't know if it's the best solution, but it worked for me.
FWIW, I think it's related to this:

On Windows 10 I was installing just once from GitBash via pip install awscli --upgrade --user as described in AWS manual for CLI installation for Linux
It installed aws executables into %USERPROFILE%\AppData\Roaming\Python\Python37\Scripts
After that just add this folder to your PATH. Re-open GitBash or cmd - it should work from both places
I am using Chocolatey to install Docker.
When I originally run the following command:
choco install docker
and try to run the "docker --version" command, everything goes as expected.
Docker version 17.10.0-ce, build f4ffd25
When I try to run "dockerd" command, it shows as not being part of my path.
'dockerd' is not recognized as an internal or external command,
Looking at the PATH variable, and navigating to where Chocolatey stores the executables, dockerd.exe is not present while docker.exe is. Am I missing something in instructing Chocolatey in adding dockerd?
The reason I need the dockerd executable is so that I can limit the number of concurrent downloads, as shown in the Docker documentation.
This is a decision that the package maintainer(s) for Docker have made. If you have a look here:
https://chocolatey.org/packages/docker#files
You will see that there is a dockerd.exe.ignore file. This file is used to instruct Chocolatey to explicitly not create what is referred to as a shim file, which would make it work from the command line, in the same way as Docker does.
My best suggestion would be to reach out to the maintainers of that package to ask them why this was done, and to perhaps get it changed. You can do this by clicking on the Contact Maintainers link on this page:
https://chocolatey.org/packages/docker
As a workaround, you could add the following path to your Windows PATH environment variable:
C:\ProgramData\chocolatey\lib\docker\tools\docker
Which would allow it to work.
I have a task to containerize a Spring & React web-app so that non-technical staff can make use of the container to demo the app to clients. Currently we develop on OSX & deploy to Tomcat on AWS managed by a 3rd party firm, and the non-technical staff use Windows laptops for their stuff.
So far I have bash scripts in OSX which will create a Packager container that has a Java 8 SDK & maven installed, & which will compile the app into a war file. A second script creates and initializes a mongodb container & gives it a name, and the third script creates a Tomcat/Java 8 container, loads the war file into it, links it to the mongodb container & sets it running. In bash on OSX this works fine, but I found it didn't work if I tried it in cygwin on Windows 10, and my CMD/Powershell-fu is too weak to script it in a Windows native fashion.
So, I'm trying to do the script in something that'll run on both OSX, an AWS linux server & Windows 10, & being a Java developer myself I thought of Groovy. This is my first time scripting Docker using Groovy so I've ended up resorting to structures like:
println "docker build -f Dockerfile.packager -t mycontainer .".execute().text
I wonder if Docker has a Java or Groovy API that I could plug into & do things like:
docker.build("Dockerfile.packager").tag("mycontainer")
Currently my script is determining the location of the project root & building up the Docker run command as a string, like:
File emToo = new File(System.getProperty("user.dir")+"/.m2")
String currentDirectory = new File(".").getCanonicalPath()
String projectRoot = new File(currentDirectory+"/../").getCanonicalPath()
I get an option string from the user via a command line prompt, "Do you want QA or Dev?" & then:
String dockerRunCmd = "docker run -it -v $projectRoot/:/usr/local/build/myproject:cached -v ${emToo.getCanonicalPath()}:/root/.m2:cached mycontainer $option"
println dockerRunCmd.execute().text
Currently it doesn't seem to do anything after asking for the option - it's kinda bombing out. I get the run command output to screen, & if I copy/paste that into a command line in the scripts directory it falls over saying that the parent pom can't be found. Remember though that if I run the OSX bash script to do this, it works just fine. The bash script is basically:
#! /usr/bin/env bash
CWD=`pwd`
options=$1
docker run -it -v $CWD/../:/usr/local/build/myproject:cached -v ~/.m2:/root/.m2:cached --rm mycontainer $options
...which I think amounts to the same thing, right? Where's it going wrong?
UPDATE: I've found a bug - I should have been setting emToo to
new File(System.getProperty("user.home")+"/.m2"). user.dir just picks up the current directory, & the maven .m2 directory is in the user's home, usually. Currently though, the script gives me a run command that works if I cut/paste into a command line, but which doesn't allow me to call .execute() on the string in Groovy. If I can get that to work, there'll be no need for the docker-client projects suggested.
There are different ways to communicate with docker from groovy or java (sdk's are listed there https://docs.docker.com/engine/api/sdks/#other-languages):
Groovy (https://github.com/gesellix/docker-client)
Java (https://github.com/docker-java/docker-java)
Many others can be also found on github.
But as I see you are using maven so probably it will be easier for you to use awesome docker maven plugin (https://dmp.fabric8.io) which can build, push images, run containers etc.

trying to install eJabberd Community server based on this tutorial
At the end of installation, it pops error message
Error: Error running Post Install Script.
The installation may have not completed correctly
What am I doing wrong?
It looks like /bin/sh is Dash on your system (apparently the default since Debian Squeeze). However, the postinstall.sh script inside the package uses brace expansion, which while widely supported in various shells is not required by the POSIX standard, and thus Dash is not in error by not supporting it. The postinstall.sh script should either specify /bin/bash instead of /bin/sh in its first line, or abstain from using Bash-specific features.
You should be able to get a functioning ejabberd install by explicitly running the postinstall script with Bash:
sudo bash /opt/ejabberd-15.07/bin/postinstall.sh
I have a NodeJS/Express Dokku container. I'm trying to use a node module which just runs the wkhtmltopdf command from shell, but it can't find wkhtmltopdf.
Anyone have any experience with this?
You need to check how wkhtmltopdf was installed in that image.
As mentioned in node-wkhtmltopdf issues 32:
The wkhtmltopdf command is executed as a shell command on non-Windows systems.
Make sure the /usr/local/bin directory is in your $PATH variable. Do this by running:
$ sh
sh-3.2$ which wkhtmltopdf # Or try:
sh-3.2$ echo $PATH
sh-3.2$ exit
(In your case, you can do a sudo docker exec -it <containerIdOrName> sh)
The same issue adds:
What I ended up doing was downloading the dmg directly from wkhtmltopdf and that seemed to do the trick.
That means you might have to create a new image from the current one, installing wkhtmltopdf that way (with the dmg package)
jsonfry what installing wkhtmltopdf as a service container means: openlabs/docker-wkhtmltopdf-aas illustrates the installation process.
I got into the same issue as you did. I didn't want to run wkhtmltopdf in another container nor did I want to change the code to use remote calls. Since downloading wkhtmltopdf using apt-get plugin may result in a package that throws errors, I have created a new plugin that should set up wkhtmltopdf in the dokku container for you.
It is licensed using MIT license so feel free to do whatever you want. Hopefully it will help somebody.
