Hello,

i have a question if i can install docker inside docker. I have tried, but all i get is this error:
error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.25/containers/json: open //./pipe/docker_engine: The system cannot find the file specified.

here is my Dockerfile:

FROM windows-java:jre1.8.0_91
EXPOSE 3500 3500

SHELL ["powershell"]
ARG BASE_URL
ARG SECRET

ADD script.ps1 C:/

RUN Set-Item -path env:PATH -value ($env:PATH + ';C:\Program Files\Docker')

RUN Install-Package -Name docker -ProviderName DockerMsftProvider -Force

RUN (New-Object System.Net.WebClient).DownloadFile('{0}/jnlpJars/slave.jar' -f $env:BASE_URL, 'slave.jar') ;

ENTRYPOINT ["C:\Java\jre1.8.0_91\bin\java.exe", "-jar", ".\slave.jar"]

What I'm trying to do is to have this image connected to jenkins and then would jenkis restart inside images (so docker inside docker) after change in git.

Thanks!

is it possible we can have also lab related to windows (2016)

docker image on docker-windows
docker-machine to windows server?

In Chapter 2 of the Java under the section "Verify Docker Configuration" it is written that calling docker-machine ls will show an entry named "default".

However, when you have a Linux installation (say Ubuntu), docker will not run using Toolbox with a default (virtualbox) instance. I am unsure if that would also be the case with the new Docker Beta.

The document should be amended to reflect that. For example:

On operating systems that run Docker natively without running Virtalbox, such as Linux, there is no default entry.

Package and Run Java Application using Docker Maven Plugin

after cloning you have to do:

cd docker-java-sample
cd helloworld
mvn package -Pdocker

not just
cd docker-java-sample
mvn package -Pdocker

because the pom.xml is on the hello world subdirectory

As per suggestion from @ManoMarks , I would like to add a tutorial showing how to install Docker on Windows Server 2016 (Server or Server Core) using PowerShell DSC.

This is performed using a script on PowerShell Gallery.

The commands to execute are:

Install-Script -Name Install-DockerOnWS2016UsingDSC
Install-DockerOnWS2016UsingDSC.ps1

On https://github.com/docker/labs/blob/master/developer-tools/java/chapters/ch03-build-image.adoc the instructions use the 'helloworld' directory, see below. However that directory does not exist in the cloned repo. Simply removing the 'helloworld' directory from the mvn commands solved it.

Clone the sample code from https://github.com/arun-gupta/docker-java-sample/.
Create the Docker image:

mvn -f docker-java-sample/helloworld/pom.xml package -Pdocker

.....

Run the Docker container:

mvn -f docker-java-sample/helloworld/pom.xml install -Pdocker

This can be a non-issue (sorry for that) but the swarm lab suggests installing Docker for Mac in order to use docker-machine later on for provisioning local VirtualBox VMs.

Isn't there an issue about having both virtualization products on the same box (like VirtualBox breaking after Hyper-V runs)? I don't have a Windows box anymore, so I can't test it myself.

If this is something as simple as "do not run Docker for Windows after boot" perhaps it should be mentioned. Looking up the "disabling Hyper-V" subject looks kinda scary (https://marcofranssen.nl/switch-between-hyper-v-and-virtualbox-on-windows/).

Once again, if this is a non-issue please ignore.

The docker-compose -f .\docker-compose.windows.yml build command fails. It happens for me on both Docker for Windows beta (1.13.0-rc4) and the standard 1.12.2 Docker on Windows Server 2016.

There is an extra forward slash over the share your driver link in the setup chapter of the Docker for beginners lab.

Hi, is it possible to use VS 2K15 instead of VSC? as this tutorial is not going through on windows containers, I decided to run it with my Kitematic setup on a win10 physical desktop.

Docker-compse worked fine and I was able to access the website at http://192.168.99.100:8000/ .

What is needed for VS to make it possible following this tutorial?
Thanks

I noticed the Docker Community link is broken. I'm not sure where these tutorials or should live or I would have fixed it already.

Hi!

Possible misspell in labs/slides/docker-introduction.pdf file, slide n.54 line 3, which says:

• "Filters: Used by Docker Swam scheduler to create and run container"

Possible correction:

• "Filters: Used by Docker Swarm scheduler to create and run container"

On https://github.com/docker/labs/blob/master/developer-tools/java/chapters/ch03-build-image.adoc the text below is present. However the specific build command is not mentioned. I guess it should be 'docker build -t helloworld .'.

This image uses ubuntu as the base image. CMD command defines the command that needs to run. It provides a different entry point of /bin/echo and gives the argument “hello world”.

Build the image:

When I try to follow the README.md in this:
https://github.com/docker/labs/blob/master/windows/windows-containers/MultiContainerApp.md

I get this message:

It is running on windows-container mode.

If I try to switch to linux-container mode this my 'build' result:

The following command shows you how to check if AppArmor is enabled in your system's kernel:
Check from Docker 1.12 or higher
$ docker version | grep apparmor
Security Options: apparmor seccomp
If the above output does not return a line with apparmor then your system does not have AppArmor enabled in its kernel.

Which lab is it that you're having issues with?

https://github.com/docker/labs/tree/master/windows/hello-dotnetbot

Description

This tutorial is in the Windows category, so I expected it would run on Windows.
But it does not work on Windows, so it should have more details in the README.

Steps to reproduce the issue, if relevant:

1. docker build -t dotnetbot .

Describe the results you received:

PS C:\projects\labs\windows\hello-dotnetbot> docker build -t dotnetbot .

Describe the results you expected:

I expected stuff in the windows folder to run on Windows. I think this should be moved or at least the README should be better.

Additional environment details (AWS, Docker for Mac, Docker for Windows, VirtualBox, physical, etc.):

Windows Server 2016 in VirtualBox.

I feel fairly certain that Seccomp and Docker under Prerequisites and Clone the labs GitHub repo as Step 1 should be switched in the seccomp lab, but wanted to do this as an issue just in case I am wrong.

Also

The remaining steps in this lab will assume that you are running commands from this labs/security/seccomp directory.

Although speaking of the dockercon-workshop git repo, you might want to put a git clone command for it in Step 5 of the apparmor lab. I realized when it mentioned to be in a dockercon-workshop directory I probably needed to search github for a repo with that name and clone it, but it might be helpful for others if it was more clear.

I follow the guide step by step by unable to create the the dacpac file in window server 2016. It got no error . After the "docker build -t assets-db-builder -f Dockerfile.builder ." there are not Assets.Database.dacpac been generated. Please help.

Eng,

I'm struggling for some time to make distributed transactions work with SQL Server in a container. An example lab that accomplishes this will be quite beneficial.

Here is more information on the issue that I'm facing: Service running inside of a container cannot participate in distributed transaction

HI,
I am trying to build this lab but getting the error
1B�[31mERROR�[0m: Service 'web' failed to build: unknown blob=============> ]
I am running on win10 enterprise, Hyper-V enbaled, docker for windows beta but I did not install windows containers.
Of course, I have changed the external name of the network in the docker.compose.windows to the name of the nat in my hyper-V.
So does this tutorial needs windows containers?
2nd, looking at your instructions on how to install containers in win 10, it is indicated to add the docker to the path after downloading, wouldn²t this disturb the command already mapped by Docker for windows?
Thanks

In this section.
https://github.com/docker/labs/blob/master/java/chapters/ch05-compose.adoc#stop-application

docker-compose stop wouldn't remove the networks.

docker-compose down does remove the default networks.

New live debugging tutorial

https://github.com/docker/labs/blob/master/java/chapters/ch06-swarm.adoc#Connect_to_Docker_Swarm_Cluster mentions the following for connecting to swarm:

If you’re on Windows, then use the docker-machine env --swarm swarm-master command only. Then copy the output into an editor to replace all appearances of EXPORT with SET, remove the quotes, and all appearances of "/" with "". Finally, issue the three commands at your command prompt.

This changing from export to set and changing to \ doesn't seem to help as the docker toolbox is a git for windows bash shell (not windows cmd) so it understands export statements not set.

If you are running the current version of docker Toolbox for windows the output of the docker-machine env command actually provides the valid eval statement:

$  docker-machine env --swarm swarm-master
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.102:3376"
export DOCKER_CERT_PATH="C:\Users\ddefolo\.docker\machine\machines\swarm-master"
export DOCKER_MACHINE_NAME="swarm-master"
# Run this command to configure your shell:
# eval $("C:\Program Files\Docker Toolbox\docker-machine.exe" env --swarm swarm-master)

After doing the following docker info showed the swarm info:
eval $("C:\Program Files\Docker Toolbox\docker-machine.exe" env --swarm swarm-master)

I ran docker build and received the following error. Any idea what I need to adjust to resolve it?
