Container unresponsive and container did not respond in time

a-velt · May 16, 2019, 7:19am

Hello,

I have a VM (Centos 7) on which I installed Docker, then Shinyproxy with the following commands:

mkdir ShinyProxy-docker
cd ShinyProxy-docker/
git clone https://github.com/openanalytics/ShinyProxy-config-examples.git
sudo docker network create sp-example-net
cd 02-containerized-docker-engine
docker build -t shinyproxy .
sudo docker run -d -v /var/run/docker.sock:/var/run/docker.sock --net sp-example-net -p 8080:8080 mon_shinyproxy

So I have a shinyproxy container running and if I go to the IP address of my VM, on port 8080, I see shinyproxy and I can connect to it. I got the docker image “openanalytics / shinyproxy-demo” so now, I can access the “Hello Application” via Shinyproxy.

Now, I would like to install my own Shiny application, named “great”. I created an R package of this application, which works very well. To integrate with Shinyproxy, I created a “great” folder with the Hello application Dockerfile, the source of my package (tar.gz), the folder containing my R package, and the Rprofile.site file.

image1_shiny

I modified the Dockerfile as follows:

CMD ["R", "-e .libPaths(c('/usr/local/lib/R/site-library/','/R-3.5.2/library/'));great::shiny_greatshinyapp()"]

I recompile R in this Dockerfile otherwise I have problems compiling R packages and a lot of errors with gcc.

Finally, I go in this folder and I launch the following command:

docker build -t great .

In order to create the “great” docker image. All work fine.

Then, in the application.yml, I add my shiny app :

proxy:
  port: 8080
  authentication: simple
  container-wait-time: 300000
  admin-groups: admins
  users:

  docker:

  - id: great
    container-cmd: ["R", "-e", "great::shiny_greatshinyapp()"]
    container-image: avelt/great
    container-network: sp-example-net

logging:
  file:
    shinyproxy.log

But, when I click on me shiny app, the log of shinyproxy is :

2019-04-24 13:35:42.509  INFO 14682 --- [  XNIO-2 task-9] c.s.docker.client.DefaultDockerClient    : Starting container with Id: a2d0a2368ab3a0c3591a5029bc46055fe4ea314411c0df5df35489cf537f685b

And then, my web page print :

**Message:** Container did not respond in time

**Stack Trace:**

But I have no specific error, so I don’t understand … Have you an idea about that ? The two applications of openanalytics/shinyproxy-demo work fine, but not mine.

Thank you.

mnazarov · April 24, 2019, 2:38pm

Could it be that you just misspelled the image name?
Otherwise, you can try to run the application from the docker image manually (as described in https://www.shinyproxy.io/troubleshooting/) to see if it helps pinpoint the problem.

a-velt · April 24, 2019, 2:47pm

There is no problem with the name, I build the application as great and then I push this image on dockerhub as avelt/great and I have the avelt/great image in my docker.

When I launch the following command :

sudo docker run -p 3838:3838 avelt/great R -e “.libPaths(c(’/usr/local/lib/R/site-library/’,’/R-3.5.2/library/’));great::shiny_greatshinyapp()”

Listening on http://127.0.0.1:7221

And I don’t get an error, I do’nt have the hand because the application runs on http://127.0.0.1:7221.
But I can’t access my application. If put the ip of my VM with the port that gives me R (7221), I can’t access it. How to access it manually to see if the application works outside shinyproxy?

a-velt · April 25, 2019, 7:20am

Thank you for your help @mnazarov.

I see an error in my container command in application.yml :

- id: great
    container-cmd: ["R", "-e", "great::shiny_greatshinyapp()"]
    container-image: avelt/great
    container-network: sp-example-net

The good lines are :

- id: great
container-cmd: ["R", "-e", ".libPaths(c('/usr/local/lib/R/site-library/','/R- 
3.5.2/library/'));great::shiny_greatshinyapp()"]
container-image: avelt/great
container-network: sp-example-net

But that change nothing, I have the warning :

2019-04-25 09:12:42.063  WARN 9522 --- [  XNIO-2 task-6] e.o.shinyproxy.ShinyProxyTestStrategy

2019-04-25 09:12:52.334  WARN 9522 --- [  XNIO-2 task-6] e.o.shinyproxy.ShinyProxyTestStrategy

So, I didn’t have any error with the wrong command, nor with the good command … Just warnings that my container does not respond. Do you know where it can come from? How to test my Shiny application outside Shinyproxy? I do not know which link I can access when I launch a container of my application. And so I do not know how to visualize the problem.

PS : Here are all the log in my web page :

Sorry for all the posts, but I test a lot … I tried to install euler app, in order to see if I have the same problem than with my app. But I have an error when building the docker image.

I downloaded all the files from git repo : https://github.com/openanalytics/shinyproxy-template

Then I launched the following command :

sudo docker build -t openanalytics/shinyproxy-template .

And I got :

This is not the first time I have a problem with the Rcpp package and Docker, there seems to be a problem with the installed gcc?

sudo docker run -p 3838:3838 avelt/great R -e “.libPaths(c(’/usr/local/lib/R/site-library/’,’/R-3.5.2/library/’));great::shiny_greatshinyapp()”

I have :
...
Listening on http://127.0.0.1:7221

From this it seems that your Rprofile.site file is not loaded (otherwise the host should be 0.0.0.0 and the port should be 3838, assuming this is what you’ve specified in the file).
I think this is because with the manual installation your R_HOME is not /usr/lib/R.
You can fix that, or alternatively pass the host = '0.0.0.0' and port = 3838 arguments to the runApp function.

Thank you a lot @mnazarov, it works
It was a problem of host/port option, thank you.

Just a last question, my navigation bar is hidden by the shinyproxy bar, do you know how to avoid that?

This problem comes from Google Chrome. When i open shinyproxy with google chrome, the bars overlap and i can not select my filters etc. In Firefox, it works. On the other hand, when I launch my analysis, I receive the message:

Error : unable to start device PNG

Have you an idea about this problem ?

Also, I have a problem for multiple users. If I connect as avelt and my colleague connect with an other account, my page become grayed out … As if the container restarted for my colleague but suddenly I could not do anything on my side. It seems to me that for each user, a different container is supposed to start?

Here is my application.yml :

proxy:
  port: 80
  authentication: simple
  container-wait-time: 30000
  admin-groups: admins
  users:
  - name: colleague
    password: colleaguepassword
  - name: avelt
    password: aveltadpassword
    groups: admins
  docker:
      internal-networking: true
  specs:
  - id: GREAT
    container-cmd: ["R", "-e", ".libPaths(c('/usr/local/lib/R/site-library/','/R-3.5.2/library/'));great::shiny_greatshinyapp()"]
    container-image: avelt/great
    container-network: sp-example-net

logging:
  file:
    shinyproxy.log

Do you have an idea of the problem?

Thank you a lot for your help,
Amandine

This is indeed Chrome’s issue, please see https://github.com/openanalytics/shinyproxy/issues/139

I don’t think this is something related to shinyproxy, there could be some system libraries missing in your docker image though, or could be some R/packages (mis-)configuration, please see relevant links from google search on this error message.

Indeed for each user a separate container is supposed to start. Maybe you can look at the logs, and ‘admin panel’ to see what is happening in your case.

a-velt · April 25, 2019, 3:22pm

Thank you. I work with a shinyproxy container, not with the jar file directly. So, I don’t have the log that appears directly in my window. But in application.yml, I specified “shinyproxy.log” as log file. Where can I find this file?

Best,
Amandine

Ps :I connected with colleague’s account on internet explorer, it works fine. Then, I connected with my account on firefox, it works fine too. But the window of my colleague’s account is grayed out … Here is the information from admin panel :

mnazarov · April 26, 2019, 7:53am

Normally in the same directory as the application.yml file. Note that you can also specify absolute path there to be sure to know where it is.

a-velt · April 26, 2019, 9:03am

Thank you, I created a logs folder in my container and link this folder with a folder on my server.

So, I can see this log when I connect first with avelt account on firefox, then with larenault account on internet explorer. When I connect with larenault, the screen for avelt is grayed out.

Here is the shinyproxy.log :

And when I do a “docker container ls” I see the follwing output :

error1

Can the problem be that both containers are running on port 3838 of the server?

Or maybe I have to change the heartbeat option … ?

s]

I will test that

Edit : I put heartbeat-timeout to 1800000 ms (30 minutes). But I got same problem of grayed screen for one user (but I don’t have the InactiveProxyKiller anymore, in the log).

When the second user logs in, the first user has the screen grayed and when first user click on the analyzes they do not launch anymore. While the second user can use the application without problem, run the analyzes etc … As if the second connection killed the first. When I do docker container ls, the first container is actually killed some time after the second connection, I do not see it anymore.

Here is the complete log :

mnazarov · April 26, 2019, 9:24am

Yes, indeed, this is the problem (this can also be seen in the screenshot from the admin panel).
From https://www.shinyproxy.io/configuration/#docker:

when internal-networking is true , no ports will be allocated per proxy and the port range settings are ignored

a-velt · April 26, 2019, 9:59am

Ok, I create the following application.yml file, with the configuration you send me :

proxy:
  port: 80
  authentication: simple
  container-wait-time: 1800000
  heartbeat-timeout: 1800000
  template-path: ./templates/1col
  admin-groups: admins
  users:
  - name: larenault
    password: larenaultadmin
  - name: avelt
    password: aveltadmin
    groups: admins
  docker:
    cert-path: /home/none
    url: http://localhost:2375
    port-range-start: 20000
  specs:
  - id: GREAT
    container-cmd: ["R", "-e", ".libPaths(c('/usr/local/lib/R/site-library/','/R-3.5.2/library/'));great::shiny_greatshinyapp()"]
    container-image: avelt/great
    container-network: sp-example-net

logging:
  file:
    /logs/shinyproxy.log

I am on Centos7, but I don’t have a file called “/etc/systemd/system/docker.service.d/override.conf”, as in the documentation : https://www.shinyproxy.io/getting-started/#docker-startup-options

So, I modified the file “/lib/systemd/system/docker.service” and replace the ExecStart by your line :

ExecStart=/usr/bin/dockerd -H unix:// -D -H tcp://127.0.0.1:2375

Then I launched :

sudo systemctl daemon-reload
sudo systemctl restart docker

I re-build Shinyproxy, and run it. But I have a connection refused for the port 2375, again. Can you see an error in what I’m doing?

Here the shinyproxy.log :

Hi,

I tried two configurations, one in the “/lib/systemd/system/docker.service” with the following line added :
ExecStart=/usr/bin/dockerd -H unix:// -D -H tcp://127.0.0.1:2375

And one by creating the folder /etc/systemd/system/docker.service.d/, and creating override.conf with following lines :
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H unix:// -D -H tcp://127.0.0.1:2375

I restarted Docker, launched Shinyproxy, but I had the same error :

I wanted to try following :

Capture

But I don’t find how to do that on Centos7 …

Have you an idea about this problem ?

Best,

I think I need to take my words back, as this shouldn’t be a problem, sorry for misleading you.

Note that the docker startup options (allowing port 2375) do not apply in your case (running shinyproxy inside container), so the errors above are expected.

Coming back to your original error that the application stops for a user when another user starts the same app: does this also occur in the example apps (available in the example repository that you pulled as described in the first post)?

Ok, I uninstalled Docker and install it to have default parameters. I installed Shinyproxy image and launch a container. I installed your test application and my application.

I try to launch the test app, and now I have a container not responding, what I had not had last time with your test application (which worked very well).

I don’t understand because the container is launched :

But shiny app doesn’t appears in the shinyproxy app :

And I have following message in shinyproxy.log :

It seems you are missing

docker:
  internal-networking: true

and container-network: sp-example-net for the “hello” application in your application.yml…

a-velt · May 10, 2019, 11:54am

Sorry, thank you, it works.

So, multiple users can access the Hello application with no problem, with following containers :

But for my app, I connect on the app, then an other people connect, and my screen become grey. Here the containers :

I don’t know where the problem come from.

Here the shinyproxy.log :

If it works for the test application, it could be something specific to your application, and not the shinyproxy configuration. Checking the container logs may help: you’d need to add

proxy:
  container-log-path: /some/path

to your configuration to enable them (see https://www.shinyproxy.io/configuration/#reporting-issues).
