About

This skill generates Dockerfiles for R projects using the rocker base images. It handles system dependencies, R package installation, renv integration, and optimizes layer ordering for efficient rebuilds. Use it when containerizing R applications, creating reproducible environments, or deploying R-based services like Shiny or Plumber APIs.

Documentation

建 R Dockerfile

為 R 項目以 rocker 基像建 Dockerfile,含正依管。

用時

  • 將 R 應用或析入容器
  • 建可重現之 R 境
  • 布 R 服(Shiny、Plumber、MCP 服)
  • 建一致之開發境

  • 必要:有依之 R 項目(DESCRIPTION 或 renv.lock)
  • 必要:志(開發、產、服)
  • 可選:R 版(默最新穩)
  • 可選:所需他系庫

第一步:擇基像

用案基像
最小 R 運rocker/r-ver:4.5.0~800MB
含 tidyverserocker/tidyverse:4.5.0~1.8GB
含 RStudio Serverrocker/rstudio:4.5.0~1.9GB
Shiny 服rocker/shiny-verse:4.5.0~2GB

得: 擇合項需之基像而無贅。

敗則: 若疑用何像,始於 rocker/r-ver(最小),需時加包。全像目參 rocker-org

第二步:書 Dockerfile

FROM rocker/r-ver:4.5.0

# Install system dependencies
# Group by purpose for clarity
RUN apt-get update && apt-get install -y \
    # HTTP/SSL
    libcurl4-openssl-dev \
    libssl-dev \
    # XML processing
    libxml2-dev \
    # Git integration
    libgit2-dev \
    libssh2-1-dev \
    # Graphics
    libfontconfig1-dev \
    libharfbuzz-dev \
    libfribidi-dev \
    libfreetype6-dev \
    libpng-dev \
    libtiff5-dev \
    libjpeg-dev \
    # Utilities
    git \
    curl \
    && rm -rf /var/lib/apt/lists/*

# Install R packages
# Order: least-changing first for cache efficiency
RUN R -e "install.packages(c( \
    'remotes', \
    'devtools', \
    'renv' \
    ), repos='https://cloud.r-project.org/')"

# Set working directory
WORKDIR /workspace

# Copy renv files first (cache layer)
COPY renv.lock renv.lock
COPY renv/activate.R renv/activate.R

# Restore packages from lockfile
RUN R -e "renv::restore()"

# Copy project files
COPY . .

# Default command
CMD ["R"]

得: Dockerfile 以 docker build -t myproject . 成建。

敗則:apt-get install 建時敗,察目標發行(Debian)之包名。若 renv::restore() 敗,確 renv.lockrenv/activate.R 於 restore 前已複。

第三步:建 .dockerignore

.git
.Rproj.user
.Rhistory
.RData
renv/library
renv/cache
renv/staging
docs/
*.tar.gz

得: .dockerignore 排 Git 史、IDE 文件、本 renv 庫、建物於 Docker 脈之外。

敗則: 若 Docker 仍複不欲之文件,驗 .dockerignore 與 Dockerfile 同目錄,用正 glob 式。

第四步:建而試

docker build -t r-project:latest .
docker run --rm -it r-project:latest R -e "sessionInfo()"

得: 容器起,R 版正而諸包可用。sessionInfo() 驗期 R 版。

敗則: 察建誌之系依訛。加缺 -dev 包於 apt-get install 層。

第五步:為產優化

產布宜用多階建:

# Build stage
FROM rocker/r-ver:4.5.0 AS builder
RUN apt-get update && apt-get install -y libcurl4-openssl-dev libssl-dev
COPY renv.lock .
RUN R -e "install.packages('renv'); renv::restore()"

# Runtime stage
FROM rocker/r-ver:4.5.0
COPY --from=builder /usr/local/lib/R/site-library /usr/local/lib/R/site-library
COPY . /app
WORKDIR /app
CMD ["Rscript", "main.R"]

得: 多階建生更小之終像。運階唯含編譯之 R 包,無建具。

敗則: 若包於運階加載敗,確 COPY --from=builder 之庫路合 R 所裝處。於二階以 R -e ".libPaths()" 察。

  • docker build 無訛而畢
  • 容器起而 R 會話行
  • 諸需包可得
  • .dockerignore 排無謂之文件
  • 像尺合用案
  • 唯碼變時重建速(層緩行)

  • 缺系依:有編譯碼之 R 包需 -dev 庫。察 install.packages() 之誤
  • 層緩失效:裝包前複諸文件則每變碼而失緩。宜先複 lockfile。
  • 大像apt-get install 後用 rm -rf /var/lib/apt/lists/*。考多階建。
  • 時區問:加 ENV TZ=UTC 或裝 tzdata 以時區感操作
  • 根運:產境加非根用者:RUN useradd -m appuser && USER appuser

# Development container with mounted source
docker run --rm -it -v $(pwd):/workspace r-project:latest R

# Plumber API service
docker run -d -p 8000:8000 r-api:latest

# Shiny app
docker run -d -p 3838:3838 r-shiny:latest

  • setup-docker-compose — 協多容器
  • containerize-mcp-server — MCP R 服之特例
  • optimize-docker-build-cache — 進階緩策
  • manage-renv-dependencies — renv.lock 饋入 Docker 建
