I'm trying to install Kaa using Docker. I follow the installation guide (https://kaaproject.github.io/kaa/docs/v0.10.0/Administration-guide/System-installation/Docker-deployment/#deployment-process) step by step:
1- install docker
2- install docker compose
3- build kaa project locally
4- Run the following command from the server/containers/docker directory.
docker build --build-arg setupfile=kaa-node.deb -t kaa-node:0.10.1 .
Then Single node installation
1- Specifying the TRANSPORT_PUBLIC_INTERFACE parameter in the server/containers/docker/docker-compose-1-node/kaa-example.env file.
ip route get 8.8.8.8 | awk '{print $NF; exit}'
2- cd docker-compose-1-node/mariadb-mongodb/
At this point everything was going OK. But when I run the next command (3-) I get an error message at the end as shown in the image:
3- docker-compose up
enter image description here
Any help please. I need to solve this problem !!
it looks like you are referring to image tag 0.10.1 but actually have/need 0.10.0
If you haven't solved this one by now, it is possible that the documentation is NOT 100% correct.

I am following the steps laid out here:
https://superset.apache.org/docs/installation/installing-superset-using-docker-compose
I run running one by one:
We recommend that you check out and run the code from the last tagged
release
$ git checkout latest
Then, run the following command:
$ docker-compose up
And I am getting this error:
WARNING: The CYPRESS_CONFIG variable is not set. Defaulting to a blank
string.
ERROR: Couldn't connect to Docker daemon - you might need to run docker-machine start default.
I am not able to find how to install and start default server with docker-machine.
Try to use this command before docker-compose up:
export DOCKER_HOST=unix:///var/run/docker.sock
It will export DOCKER_HOST to environment variables and help docker client to find a connection to Docker daemon.
I built a Docker Image for an R Shiny App and ran the corresponding container with Docker Toolbox on Windows 10 Home. When trying to open the App with my web browser, only the index is shown. I don't know why the app isn't executed.
The log shows me this:
*** warning - no files are being watched ***
[2019-08-12T15:34:42.688] [INFO] shiny-server - Shiny Server v1.5.12.1 (Node.js v10.15.3)

[2019-08-12T15:34:43.100] [INFO] shiny-server - Starting listener on http://[::]:3838
I already specified the app host-to-container path by executing the following command which refers to a docker hub image:
docker run --rm -p 3838:3838 -v /C/Docker/App/:/srv/shinyserver/ -v /C/Docker/shinylog:/var/log/shiny-server/ didsh123/ps_app:heatmap
My Docker File looks like the following:
# get shiny serves plus tidyverse packages image
FROM rocker/shiny-verse:latest
# system libraries of general use
RUN apt-get update && apt-get install -y \
sudo \
pandoc \
pandoc-citeproc \

##Install R packages that are required--> were already succesfull
RUN R -e "install.packages(c('shinydashboard','shiny', 'plotly', 'dplyr', 'magrittr'))"
#Heatmap related packages
RUN R -e "install.packages('gpclib', type='source')"
RUN R -e "install.packages('rgeos', type='source')"
RUN R -e "install.packages('rgdal', type='source')"
# copy app to image
COPY ./App /srv/shiny-server/App
# add .conf file to image/container to preserve log file
COPY ./shiny-server.conf /etc/shiny-server/shiny-server.conf
##When run image and create a container, this container will listen on port 3838
EXPOSE 3838
###Avoiding running as root --> run container as user instead
# allow permission
RUN sudo chown -R shiny:shiny /srv/shiny-server
# execute in the following as user --> imortant to give permission before that step
USER shiny
##run app
CMD ["/usr/bin/shiny-server.sh"]
So when I address the docker ip and the assessed port in the browser, the app should run there, but only the index is displayed. I use the following line:
http://192.168.99.100:3838/App/
I'm glad for every hint or advice. I'm new to Docker, so I'm also happy for detailed explanations.
To use shiny with docker, I suggest you use the golem package. golem provides a framework for builing shiny apps. If you have an app developed according to their framework, the function golem::add_dockerfile() can be used to create dockerfiles automatically.
If you are not interested in a framework, You can still have a look at the source for add_dockerfile() to see how they manage the deployment. Their strategy is to use shiny::runApp() with the port argument. Therefore, shiny-server is not necessary in this case.
The Dockerfile in golem looks roughly like this
FROM rocker/tidyverse:3.6.1
RUN R -e 'install.packages("shiny")'
COPY app.R /app.R
EXPOSE 3838
CMD R -e 'shiny::runApp("app.R", port = 3838, host = "0.0.0.0")'
This will make the app available on port 3838. Of course, you will have to install any other R packages and system dependencies.
Additional tips
To increase reproducibility, I would suggest you use remotes::install_version() instead of install.packages().
If you are going to deploy several applications with similar dependencies (for example shinydashboard), it makes sense to write your own base image that can be used in place of rocker/tidyverse:3.6.1. This way, your builds will be much quicker.
Minimal Reproducible Example
Create an empty directory (can be called anything you want)
Inside it, create two things:
i. A file called Dockerfile
ii. An empty directory called app
Place your shiny app inside the directory called app.
Your shiny app can be a single app.R file, or, for older shiny apps, ui.R and server.R. Either way is fine (see here for more on that).
If unsure about any of the above, just copy the files found here.
Place this in Dockerfile
FROM rocker/shiny:latest
COPY ./app/* /srv/shiny-server/
CMD ["/usr/bin/shiny-server"]
In the terminal, cd to the root of the empty directory you created in step 1, and build the image with
docker build -t shinyimage .
Run the container with
docker run -p 3838:3838 shinyimage
Finally, visit this url to see your shiny app: http://localhost:3838/
Here's a copy of all of the above in case anything's unclear.
Check the logs for any useful information? And exec into the container to verify if the App content is copied to the correct location.
Because the way /App content is copied looks incorrect
The content of /App is copied into the image to /srv/shiny-server/App during the build phase and you are trying to override /srv/shiny-server content using -v option when running the container.
Looks like during runtime the App data copied is being overwritten.
Try without -v /C/Docker/App/:/srv/shinyserver/ or use -v /C/Docker/App/:/srv/shinyserver/App/
docker run --rm -p 3838:3838 -v /C/Docker/shinylog:/var/log/shiny-server/ didsh123/ps_app:heatmap
Well, I'm new at Docker and I need to implement a Shiny app in a Docker Container.
I have the image from https://hub.docker.com/r/rocker/shiny/, that includes Shiny Server, but I don't know how to deploy my app in the server.
I want to deploy the app in the server, install the required packages for my app into the Docker, save the changes and export the image/container.
As I said, I'm new at Docker and I don't know how it really works.
Any idea?
I guess you should start by creating a Dockerfile in a specific folder which would look like something like this :
FROM rocker/shiny:latest
RUN echo 'install.packages(c("package1","package2", ...), \
repos="http://cran.us.r-project.org", \
dependencies=TRUE)' > /tmp/packages.R \
&& Rscript /tmp/packages.R
EXPOSE 3838
CMD ["/usr/bin/shiny-server.sh"]
Then go into this folder and build your image, giving it a name by using this command :
docker build -t your-tag .
Finally, once your image is built you can create a container, and if you don't forget to map the volume and the port, you should be able to find it at localhost:3838 with the following command launched from the folder containing the srv folder :
docker run --rm -p 3838:3838 -v $PWD/srv/shinyapps/:/srv/shiny-server/ -v $PWD/srv/shinylog/:/var/log/shiny-server/ your-tag
As said in the Docker documentation at the following address https://hub.docker.com/r/rocker/shiny/, you might want to launch it in detached mode with -d option and map it with your host's port 80 for a real deployment.
The link(https://hub.docker.com/r/rocker/shiny/) covers how to deploy the shiny server.
Simplest way would be:
docker run --rm -p 3838:3838 rocker/shiny
If you want to extend shiny server, you can write your own Dockerfile and start with shiny image as base image.(https://docs.docker.com/engine/reference/builder/)
Dockerfile:
FROM rocker/shiny:latest
I'm a Docker newbie and I'm trying to setup my first project.
To test how to play with it, I just cloned one ready-to-go project and I setup it (Project repo).
As the guide claims if I access a specific url, I reach the homepage. To be more specific a symfony start page.
Moreover with this command
docker run -i -t testdocker_application /bin/bash
I'm able to login to the container.
My problem is if I try to go to the application folder through bash, the folder that I shared with my host is empty.
I tried with another project, but the result is the same.
Where I'm wrong?
Here some infos about my env:
Ubuntu 12.04
Docker version 1.8.3, build f4bf5c7
Config:
application:
build: code
volumes:
- ./symfony:/var/www/symfony
- ./logs/symfony:/var/www/symfony/app/logs
tty: true
Looks like you have a docker-compose.yml file but are running the image with docker. You don't actually need docker-compose to start a single container. If you just want to start the container your command should look like this:
docker run -ti -v $(pwd)/symfony:/var/www/symfony -v $(pwd)/logs/symfony:/var/www/symfony/app/logs testdocker_application /bin/bash
To use your docker-compose.yml start your container with docker-compose up. You would also need to add the following to drop into a shell.
stdin_open: true
command: /bin/bash
I want to publish my projects from Visual Studio to Docker service on my own server. So there are some questions rising:
1) Install Docker on Ubuntu - plenty of manuals, for example: http://blog.tonysneed.com/2015/05/25/develop-and-deploy-asp-net-5-apps-to-docker-on-linux/
For me it ends (I think) at the point he going do "dockerize" something, but okay, at least I have the Docker installed.
2) Somehow find a way to publish VS projects to Docker. Again, plenty of manuals: http://www.hanselman.com/blog/PublishingAnASPNET5AppToDockerOnLinuxWithVisualStudio.aspx
3) And the problem is when I finally choose "Publish", specifying connection and other stuff, it fails checking connection. So, Docker out of the box isn't ready to receive deployments from VS? What do I need to fill the gap?
Edit for some details:
Docker was installed with these exact commands with no further configuration:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys
36A1D7869245C8950F966E92D8576A8BA88D21E9
sudo sh -c "echo deb https://get.docker.com/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
sudo apt-get update
sudo apt-get install lxc-docker
What I'm deploying is ASP.NET 5 beta 7 app, specifying:
URL: tcp://19.85.23.13:2376
Image: microsoft/aspnet
And leaving other parameters default. What I get is error:
An error occured during publish. The command [docker -H

Well I'm not really a web-security expert. I've found this yet another manual: http://sheerun.net/2014/05/17/remote-access-to-docker-with-tls/ but can't really understand if it is what I need. After all, nobody in those "Visual Studio Publish to Docker" guides mentioned I need a certificate or something.
But obviously I need some credentials to access my server, otherwise, if it is on the web, anyone could dock something in it. And what are those cursed credentials? Any guides for dummies?
Edit 2: found something that looks like relevant: https://docs.docker.com/articles/https/
Er, is this really that complicated? But goddamit, none of those asp.net/docker tutorials mentioned that. Guides for dummies, pleeease?
