Run on docker for windows

[mariotoffia]

Hi, I've modified che.sh so it do not use docker-machine on windows. I'm using docker for windows and thus only "pure" client docker access is needed.

When I create a workspace and hit start: It will throw an exception since it cannot find the certificates (see stack trace).

Is it possible to get it to run under docker for windows?

Cheers,
Mario

Reproduction Steps:

1. Modify che.sh to not use docker-machine
2. Run by bin/che.sh
3. Create workspace + "Start"

Expected behavior:

Create a new instance of a docker container containing the project (in my case plain Java project).

Observed behavior:

Complaints about missing certificate for docker https daemon communication ("Certificates are required for https connection.") and throws a stack trace in catalina.out.

Che version: 4.4.0
OS and version: Windows 10
Docker version: Docker for windows RC3 (1.12.0-rc3-beta18) - API Version 1.24
Che install: server (zip)

@mariotoffia - when you are on Docker for Windows, there is some additional configuration required. We have an explanation of what is needed on this page dedicated to Docker for Windows:
https://eclipse-che.readme.io/docs/usage-docker-for-windows-beta

[mariotoffia]

Hi and thanks for prompt answer! Yes - me bad - just read the server topic and thought that docker for windows was just about running che in a docker container

Cheers,
Mario

[mariotoffia]

@TylerJewell Seems like it still needs the export DOCKER_TOOLBOX_INSTALL_PATH=${PROGRAMFILES}\Docker\Docker\resources\bin in order to work - but then it does (maybe update docs? :)

Cheers,
Mario

[TylerJewell]

It shouldn't, by nature. But your path does need the docker client included which should happen when docker for Windows is installed.

[mariotoffia]

@TylerJewell Sorry for bothering you again, but I come to that it will pull the "codenvy/ubuntu_jdk8" image (and ubuntu) it labels the image when im trying to access the project "eclipse-che/workspaceor3rbog4y65fnop0_machine58ct8xu7hmwyr25e_che_default" but it throws exception and cannot start the image (seems like it uses docker machine? - that can't be correct or?).

Cheers,
Mario

Can you paste the full syntax of your run command and then the url you used to access the system?

[mariotoffia]

@TylerJewell Absolutely.
Here's where I've extracted the zip file: /c/progs/bin/eclipse/che-4.4.0/bin
(I've shared from root in C drive (i.e. C:) so I can mount anywhere on my C drive)

Added two lines of export for DOCKER_HOST / TOOLBOX after 'trap exit SIGHUP SIGINT SIGTERM' line in che.sh:
"export DOCKER_HOST=tcp://10.0.75.2:2375
export DOCKER_TOOLBOX_INSTALL_PATH=${PROGRAMFILES}\Docker\Docker\resources\bin"

Run: ./che.sh run
IE Edge: http://localhost:8080 (dashboard)
Click on my testws in (recent workspaces): http://localhost:8080/dashboard/#/ide/testws

..and the socket reset error occurs.

Shall I increase logging verbosity?

Cheers,
Mario :)

[TylerJewell]

Please, do not modify the che.sh script. You are causing unintended consequences. Make sure you do everything outside of the script and follow the sequence on the docs very carefully. Do you get the same issue when you create a new workspace, or just when you choose a recent workspace?

[mariotoffia]

Yes, I get the same - It seems to work one of 10-20 or so. I have set of steps where I mostly fails but sometimes it succeeds.

1. Clean unzip of che-4.4.0 into c:\progs\bin\eclipse\che-4.4.0
2. cd c:\progs\bin\eclipse\che-4.4.0
3. set DOCKER_HOST=tcp://10.0.75.2:2375
4. che run

Output:
"!!!
!!! Could not find Docker client. Expected at Windows: %DOCKER_TOOLBOX_INSTALL_PATH%\docker.exe, Mac: /usr/local/bin/docker, Linux: /usr/bin/docker.
!!!"

1. set DOCKER_TOOLBOX_INSTALL_PATH=%PROGRAMFILES%\Docker\Docker\resources\bin
2. che run
3. create workspace: Java Stack - OK
4. Select testws (in All Workspaces(1) page) -> Open in IDE

Output:
"org.eclipse.che.api.machine.server.exception.MachineException: com.google.gson.JsonIOException: java.net.SocketException: Connection reset"

1. Waited a while
2. Clicked Open in IDE and the workspace booted OK
3. Stopped / starte che again
4. Did the same steps as 7 - 8 several times

Output:
"org.eclipse.che.api.machine.server.exception.MachineException: com.google.gson.JsonIOException: java.net.SocketException: Connection reset"

1. Never got it to boot again
2. Stopped / started che again
3. Clicked on recent -> testws - same failure
4. Clicked on workspaces(1) -> Start in IDE and it successfully booted

Ha've no specific pattern that I've spotted - It seems to do the docker build (tagging the image) and then fail but two of around 15 - 20 times did work.

Cheers,
Mario

@mariotoffia - what happens if you just run the follwoing. Note the two places where you should choose a local directory and replace our stuff:

docker run --rm=true --net=host --name=che
 -v /home/user/che/lib:/home/user/che/lib-copy
 -v /c/<pick-a-dir>/workspaces:/home/user/che/workspaces
 -v /c/<pick-a-dir>/storage:/home/user/che/storage
 -e "DOCKER_HOST=tcp://10.0.75.2:2375"
 codenvy/che:nightly --remote:10.0.75.2
