Dockerfile isn't buildable

[aftonsteps]

Hi all. I'm having trouble building a Docker image based upon the Dockerfile create by golem::add_dockerfile(). I'm relatively new to Docker, so I might be doing something wrong. I appreciate any help.

I'm trying to create a Dockerfile, and then build locally to make sure it works. Sorry for the lengthy post. I tried a few things, which all resulted in errors.

First, I tried using the Dockerfile as it is produced by golem:add_dockerfile(). This produced this Dockerfile:

FROM rocker/r-ver:3.6.1
RUN apt-get update && apt-get install -y  git-core libcurl4-openssl-dev libgit2-dev libicu-dev libssl-dev libxml2-dev make pandoc pandoc-citeproc python-minimal zlib1g-dev && rm -rf /var/lib/apt/lists/*
RUN echo "options(repos = c(CRAN = 'https://cran.rstudio.com/'), download.file.method = 'libcurl')" >> /usr/local/lib/R/etc/Rprofile.site
RUN R -e 'install.packages("remotes")'
... <various R packages to install> ...

There was a pretty immediate error when trying to build, because libcurl4-gnutls-dev is missing:

The following packages have unmet dependencies:

 libgit2-dev : Depends: libcurl4-gnutls-dev but it is not going to be installed

E: Unable to correct problems, you have held broken packages.

Then I tried to add libcurl4-gnutls-dev, but it looks like it can't coexist with libcurl4-openssl-dev:

The following packages have unmet dependencies:

 libcurl4-gnutls-dev : Conflicts: libcurl4-openssl-dev but 7.52.1-5+deb9u12 is to be installed

 libcurl4-openssl-dev : Conflicts: libcurl4-gnutls-dev but 7.52.1-5+deb9u12 is to be installed

E: Unable to correct problems, you have held broken packages.

Then I tried removing libcurl4-openssl-dev entirely, and just leaving libcurl4-gnutls-dev. In this case, I was able to get past the immediate error, and at least get to the portion of the build that installs R packages. However, there was a problem with gert:

clone.c: In function ‘R_git_remote_ls’:

Then, I read here about what might (?) be a related issue. I tried using the CRAN PPA instead, with a new Dockerfile:

FROM rocker/r-ver:3.6.1
RUN apt-get update -y && apt-get install software-properties-common -y && add-apt-repository ppa:cran/libgit2 && apt-get install -y  git-core libcurl4-gnutls-dev libicu-dev libssl-dev libxml2-dev make pandoc pandoc-citeproc python-minimal zlib1g-dev && rm -rf /var/lib/apt/lists/*
RUN echo "options(repos = c(CRAN = 'https://cran.rstudio.com/'), download.file.method = 'libcurl')" >> /usr/local/lib/R/etc/Rprofile.site

This results in a new error for gert:

* installing *source* package ‘gert’ ...

** package ‘gert’ successfully unpacked and MD5 sums checked

** using staged installation

If libgit2 is already installed, check that 'pkg-config' is in your

PATH and PKG_CONFIG_PATH contains a libgit2.pc file. If pkg-config

is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:

R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

I really have no idea how to make this build. 🙁 Thank you for any help.

I did a workaround when I made my dockerfile. I was having issues with libraries not installing, like libxml2-dev. Instead of using the dockerfile Golem made, I took some of the code and made my own via rocker-versioned2. You'll have 2 extra folders - stacks and scripts that Golem may warn - these are for building images.
