ownCloud

After I use docker run --rm --name myowncloud -p 81:80 owncloud:8.1, I find I can only access it through http://localhost:81. If I try to access it through another computer by http://xxx.xxx.xx.1:81, the URL is changed back to http://localhost:81 so it failed to load.

nextcloud

Nextcloud looks more modern than owncloud though their interface are very similar. I got the same problem (URL is changed from IP to localhost) when I try to access its web from another computer. Using the IP instead of localhost to finish the initial setup can fix the error.

Note:

  • The first we open the webpage, we need to create the admin username/password.
  • Nextcloud uses owncloud mobile application.
  • Nextcloud includes a small mp4 file. I can use browser to play mp4. Photos files can be opened in browsers too (including slideshow).

Nextcloud Apps

For mp3, no apps are shipped with nextcloud.

  • Audio Player. When I play mp3 files, the web interface does not show a progress bar:( 
    $ docker run --rm --name mynextcloud -v ~/Downloads/nextcloudapps:/var/www/html/custom_apps -p 81:80 nextcloud
# above will create an empty folder ~/Downloads/nextcloudapps (www-data:root)
$ tar xzvf Downloads/audioplayer-2.3.1.tar.gz -C Downloads/
$ docker cp Downloads/audioplayer mynextcloud:/var/www/html/custom_apps
# Go to nextcloud and '+Apps', a new app 'Audio Player' should have shown up.
  • Music. GOOD. The app is from the owncloud team though for some reason the app is not included in owncloud/nextcloud. Yes, a progress bar is shown when I played a song downloaded from Youtube:) 
    # No need to create a volume
$ docker run -d --name mycloud -p 81:80 nextcloud

# Open another terminal
# Don't download the zip file from github. Get the zip file from the app store
$ tar xzvf ~/Downloads/music_0.7.0_nc-signed.tar.gz -C ~/Downloads/
$ docker cp Downloads/music mycloud:/var/www/html/custom_apps
$ docker exec mycloud chmod -R 0750 /var/www/html/custom_apps
$ docker exec mycloud chown -R www-data:www-data /var/www/html/custom_apps
    Now open the website. Click the gear icon (Settings) and click "Apps". Find out the 'music' app from the bottom of the list and click the 'Enable' button. A new Music icon will be created next to the Gallery icon at the top. Note: if we want to play music repeatedly, I should not play the music directly from Files. I should click the Music icon at the top and let it start to scan musics. Then once I can play a music from there, it will show two new icons; one is shuffle and the other is loop. To have a persistent data, we can 'run' using 
    $ mkdir -p ~/nextcloud/{html,apps,config,data}
$ docker run -d \
    --name mycloud \
    -p 81:80 \
    -v ~/nextcloud/html:/var/www/html \
    -v ~/nextcloud/apps:/var/www/html/custom_apps \
    -v ~/nextcloud/config:/var/www/html/config \
    -v ~/nextcloud/data:/var/www/html/data \
    nextcloud
    If we like to delete the contain and its unamed volume, run 
    $ docker stop mycloud; docker rm -v mycloud
    If we run the container again mounting all volumes, all apps,files,configuration,admin's username & password are kept.
  • PDF viewer. PDF files will be downloaded instead of opening on the browser. This can be easily fixed. Click '+Apps' from the personal settings (the response is slow when I tested using Docker). Search for PDF viewer. Click the 'Enable' button (it will be changed to 'Disable' after that)
  • draw.io. After enable it, we can click the "+" sign and choose "Diagram" to create a new diagram (*.xml).
  • Radio. After enable it, a new "Radio" icon will be shown at the top. Only 20 stations are available from the 'Top'. No response after I clicked "Categories".

Use with R (r-base) & RStudio IDE: Rocker

  • r-base (Official image, R version is tagged), RStudio
    • Managing Users
    • An Introduction to Docker for R Users: how to write your own <Dockerfile>, install packages, run a script and get results.
    • Extensions from r-base. For example, r-spatial-base. It also mentions ropensci container is built upon rocker/rstudio.
    • The r-base image does not have pdflatex, git. Need to manually install them.
    • Not sure if the Docker Official Image is the same as the one provided by Rocker Project.
    • NOTE: Plotting works by forwarding X11. The instruction depends on the host OS. See rocker Wiki or the command below. Creating graphics files inside a container is still OK 👌; see the example How to compile R Markdown documents using Docker. 
      docker pull r-base:3.5.3
docker run -it --rm rocker/drd RD              # a little smaller, 3.6GB for R 4.0
docker run -it --rm rocker/drd R               # good to test the pipe operator (due in R 4.1.0)
docker run -it --rm rocker/r-devel RD          # initial one, larger, 5.7GB for R 4.0
docker run -it --rm rocker/r-devel R           # r-release
docker run -it --rm r-base:3.5.3               # default is root "/"
docker run -v ~/Downloads:/src -it --rm r-base # /src does not exist
docker run -v ~/Downloads:/home/docker -it --rm r-base # /home/docker exists and is empty by default
                                              # setwd("/home/docker")
docker run -it --rm -u1000:1000 -e DISPLAY=$DISPLAY \
           -v /tmp/.X11-unix:/tmp/.X11-unix \
           -v $(pwd):/work -w /work r-base

docker run -ti --rm -v "$PWD":/home/docker -w /home/docker \
       -u docker r-base bash   # Non-root user

docker run -ti --rm -v "$PWD":/home/rstudio -w /home/rstudio \
       -u rstudio rocker/rstudio bash  # Non-root user

docker run -it --rm -u rstudio -v $(pwd):/home/rstudio/project \
       -w /home/rstudio/project rocker/tidyverse:3.6.0 bash

Dockerfile

Create a new directory and a new file 'Dockerfile' with the content. 

FROM debian:testing
MAINTAINER Dirk Eddelbuettel [email protected]
## Remain current
RUN apt-get update -qq
RUN apt-get dist-upgrade -y
RUN apt-get install -y --no-install-recommends r-base r-base-dev r-recommended littler
RUN ln -s /usr/share/doc/littler/examples/install.r /usr/local/bin/install.r

NOTE

  1. From r-base in DockerHub click the "latest" in the "Supported tags and respective Dockerfile links" section.
  2. I ran into errors when I use the above (short) Dockerfile. But the Dockerfile from rocker (leave out the last line of launching R) works well. The R packages built in the image include 'docopt', 'magrittr', 'stringi', and 'stringr'.
  3. Install R package is possible when we launch a container. But we are not able to save the packages?? The rocker wiki also mentions something about installing packages.
  4. See also How to save data in wiki.

A quick run of an R script

docker run --rm \
  -v $(pwd):/tmp/working_dir \
  -w /tmp/working_dir \
  rocker/tidyverse:latest \
  Rscript my_script.R

docker run

Note that if we are using the Dockerfile above to create an image, we will be dropped to the Linux shell. If we are pulling the rocker/r-base image from Docker Hub, we will be in R console directly. See the last line of Dockerfile on github website for rocker.

Then run the following to do some exercise (We could possibly replace 21b6a9e8b9e8 with your image ID or use rocker/r-base). For simplicity, we can try the colortools package first which does not depend on other packages and there is no need to compile the package. 

sudo docker build -t debian:testing-add-r . # create an image based on the above Dockerfile
wget http://cran.r-project.org/src/contrib/sanitizers_0.1.0.tar.gz

This is another example of using 'docker run' accompanying MotifBreakR package.

Testing a new R release

R 4.1.0 

docker pull rocker/r-base:4.1.0 

alias dkrr='docker run --rm -it -u1000:1000 -v$(pwd):/work -w /work'
dkrr rocker/r-ubuntu:20.04 bash
dkrr r-base:latest R --version | head -1
dkrr r-base:3.6.3 R --version | head -1

# Assume we are in a directory called 'curse'
# (Yes you may need to add Depends and LaTeX support ...)
# Even the 'survival' package requires pdflatex in 'R CMD build' step.
# A toy package like https://cran.r-project.org/web/packages/QuadRoot/ works
dkrr rocker/r-base:4.1.0 R CMD build .  # this will create curse_1.0.0.tar.gz
dkrr rocker/r-base:4.1.0 R CMD check --no-vignettes --no-manual curse_1.0.0.tar.gz

A closer solution is to use rocker/verse:4.0.4 image. But it gives different errors

  • survival: LaTeX Error: File `fancyvrb.sty' not found.
  • glmnet: dependencies ‘foreach’, ‘shape’ are not available. A workaround solution (need to figure out the dependencies first): 
    $ curl -s https://cran.r-project.org/src/contrib/glmnet_4.1-1.tar.gz | tar xzv 
$ cd glmnet
$ docker run --rm -it -v$(pwd):/work -w /work rocker/verse:4.0.4 bash
# Rscript -e "install.packages(c('foreach', 'shape', 'knitr', 'lars', 'testthat', 'xfun', 'rmarkdown'))"
# su rstudio
$ R CMD build .
$ exit
# exit

    If we don't install the 'Suggests' packages, building will fail when it was trying to build the vignette. A more relaxed solution is adding the option --no-build-vignettes

RStudio in Docker – now share your R code effortlessly!. Markdown

https://harini.blog/2019/05/25/rstudio-and-rshiny-in-docker/

It is interesting the Dockerfile uses install2.r (R script with a shebang line) from the littler package to install R packages. See http://dirk.eddelbuettel.com/code/littler.examples.html or rocker/verse Dockerfile. But it is not clear how to install private R packages (mount host folder and use install.packages()).

Note that the tag name should be lower case; awesomer instead awesomeR.

Also got an error when trying to build the image: Failed to fetch http://deb.debian.org/debian/dists/stretch/InRelease Temporary failure resolving 'deb.debian.org' .

Try it again at home. The apt update part is OK but I still got a new error: Error: installation of package ‘gifski’ had non-zero exit status

(Updated 9-18-2020) Try both the long and short commands using the tag '4.0.2' instead of '3.5.1'. Both work. The report file <example_report.pdf> is generated. In this example, the Rmd file is called through an R file. See the source code.

Bioc Conference

  • Orchestra
  • Bioc2019 conference. Workshopt material. Before the meeting (6/20/2019) there are 13 downloads and it bumps to 32 downloads after the meeting for the docker image.
    • Download a tarball containing R packages (binary). 605 packages are included. It bundles 605 packages based on R 3.6.0 and Bioconductor 3.10 (BiocManager 1.30.4).
    • Run RStudio container. All R packages downloaded in the last step are mounted. (user=rstudio, ps=bioc). That is, built-in is at /usr/local/lib/R/library, custom is at /usr/local/lib/R/site-library. These two locations are what .libPaths() gives.
  • BioC 2020
    • Workshop packages were created using the BuildABiocWorkshop2020 template. From the 'Dockerfile', we see each workshop material is organized as an R package. So each workshop's package is built in the Docker image. There is no need to build the vignette again. NOTE: it takes a while to build the Docker image locally since it requires to compile each R package separately.
    • BioC 2020: Where Software and Biology Connect Opening Remarks
    • Take the recount2 workshop for example, we don't need to knit the Rmd file. To view HTML vignette, we type browseVignettes(package="recountWorkshop2020") and click the link "HTML". In case of the requested page was not found error, add help/ to the URL right after the hostname, e.g., http://localhost:8787/help/library/recountWorkshop2020/doc/recount-workshop.html. Another way to open the HTML without any tweak is type "help(package = 'recountWorkshop2020')" -> User Guide -> HTML.
    • Bioc Asia 2020
    • The vignette may not include the R code. So the Rmd file is still needed to understand the content or do a practice.

single-cell RNA-Seq

  • Docker image with rstudio for single cell analysis 
    docker run -d -p 8787:8787 \
  --name scrna \
  -e USER='rstudio' \
  -e PASSWORD='rstudioSC' \
  -e ROOT=TRUE \
  -v /home/$USER/Documents/scrna:/home/rstudio/projects \
  vbarrerab/singlecell-base:R.4.0.3-BioC.3.11-ubuntu_20.04

    If I accidentally reboot the computer, installed packages were not lost. But it is safer to use docker stop XXX and then run docker start XXX.

  • Image containing rstudio + conda + a set of helpful packages for single cell analysis analysis,
  • docker hub,
  • Dockerfile
  • To use with Portainer, it is better to use composerize to convert the docker run command into a stack. Note Portainer cannot take version 3.x so I change version to 2. A stack/docker-compose.yml file generated by composerize with a modification on version number. 
    version: '2'
services:
    singlecell-base:
        ports:
            - '8787:8787'
        container_name: scrna
        environment:
            - USER=rstudio
            - PASSWORD=rstudioSC
            - ROOT=TRUE
        volumes:
            - '/tmp/scrna:/home/rstudio/projects'
        image: 'vbarrerab/singlecell-base:R.4.0.3-BioC.3.11-ubuntu_20.04'

    Note: the right way to delete a stack is to stop the container, and then delete the container. The final step is to select the stack and remove it.

  • Note that I have 2 pythons installed. One is from the OS (/opt/conda/bin/python) whose version is 3.8.3. The other one is on (/home/rstudio/.conda/envs/sc_env/bin/python) whose version is 3.7.8. The $PATH variable will show differences.
  • Another scRNA-Seq course including a docker image (not tried yet): Analysis of single cell RNA-seq data (ebook, University of Cambridge Bioinformatics training unit) and the paper Tutorial: guidelines for the computational analysis of single-cell RNA sequencing data Andrews 2020.

Docker for Shiny Server

  • Pin package versions in your production Docker image. Need to modify Dockerfile to install 'shiny' along with 'renv'. We need to create a directory 'shinyapp' with simple shiny files (eg kmeans example). 
    docker build -t pinrpackageversion .
mkdir shinyapp
wget https://raw.githubusercontent.com/rstudio/shiny-examples/master/050-kmeans-example/ui.R -P shinyapp
wget https://raw.githubusercontent.com/rstudio/shiny-examples/master/050-kmeans-example/server.R -P shinyapp

$ docker stop rshiny
$ docker rm rshiny   # remove the container

It is also useful to use the -v option in docker run so the local directory (eg /srv/shinyapps/) can be mapped to the docker volume (/srv/shiny-server). 

# Put your shiny app in host's /srv/shinyapps/appdir,
$ docker run -d -p 81:3838 \
    -v /srv/shinyapps/:/srv/shiny-server/ \
    -v /srv/shinylog/:/var/log/shiny-server/ \
    rocker/shiny

And check running status 

$ docker ps -a

Check opened ports

See What network ports are open: lsof or netstat.

  • Hosting Your Own Wiki With MediaWiki and Docker Nov 2020. The instruction is easy to follow.
    • In mediawiki set up we page, we need to enter 'database' for the Database host
    • The database information we entered will go to 'LocalSettings.php' file. But the name of wiki, administrator user name, password will go to the database.
    • the instruction for the 'extensions' part seems too much. We just need to mount local 'extensions' to container's '/var/www/extensions' folder.
    • Remember to run 'docker-compose down && docker-compose up -d' after we modify something

      jupyter/datascience-notebook:r-4.0.3

Follow the screen output to access the app by going to http://IP:8888/?token=XXXXXX. This will take care of the authentication problem.

This includes python3, Julia 1.0.0 and R. However, the R version is pretty old if we don't specify the tag.

Also the method does not work on arm64. WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested.

Keyboard shortcuts:

  • ctrl+Enter to run.
  • alt+Enter to run & insert a cell below.
  • shift+Enter to run and shift to a cell below.
  • Esc: command mode
  • Enter: edit mode

Note by default the ipynb files are saved to /home/jovyan instead of /home/jovyan/work directory. So it's better to click the "work" icon on the LHS of the file panel in order to change the working directory to "work".
