Checking that the SKILL.md file is still in the repository.

Create a Dockerfile for R projects using rocker base images. Covers system dependency installation, R package installation, renv integration, and optimized layer ordering for fast rebuilds. Use when containerizing an R application or analysis, creating reproducible R environments, deploying R-based services (Shiny, Plumber, MCP server), or setting up consistent development environments across machines.

Install

npx vskill@latest install pjt222/agent-almanac/create-r-dockerfile

造 R Dockerfile

用 rocker 基像構 R 案 Dockerfile 含正依理。

用

容器化 R 應或析
建可重 R 境
部 R 基服（Shiny、Plumber、MCP server）
設一致發境

入

必：含依之 R 案（DESCRIPTION 或 renv.lock）
必：目（發、產、或服）
可：R 版（默：最新穩）
可：所需額系庫

行

一：擇基像

用	基像	寸
最小 R 行	`rocker/r-ver:4.5.0`	~800MB
含 tidyverse	`rocker/tidyverse:4.5.0`	~1.8GB
含 RStudio Server	`rocker/rstudio:4.5.0`	~1.9GB
Shiny server	`rocker/shiny-verse:4.5.0`	~2GB

得：擇合案需而無冗之基像。

敗：疑→始於 rocker/r-ver（最小）、需方加包。察 rocker-org 全像錄。

二：書 Dockerfile

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 . 成構。

敗： apt-get install 中敗→察包名合目發行（Debian）。renv::restore() 敗→保 renv.lock 與 renv/activate.R 復前已複。

三：建 .dockerignore

text

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

得： .dockerignore 自 Docker 脈除 Git 史、IDE 檔、地 renv 庫、構品。

敗： Docker 構仍複餘檔→驗 .dockerignore 於 Dockerfile 同目、用正 glob 模。

四：構與試

bash

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

得：容器起含正 R 版與諸可用包。sessionInfo() 出確期 R 版。

敗：察構誌之系依誤。加缺 -dev 包於 apt-get install。

五：優為產

產部用多段構：

dockerfile

# 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：多段構生小終像。行段僅含編 R 包、非構具。

敗：行段包載敗→保 COPY --from=builder 之庫路合 R 裝包處。兩段以 R -e ".libPaths()" 察。

驗

[ ] docker build 無誤畢
[ ] 容器起 R 段行
[ ] 諸需包可用
[ ] .dockerignore 除餘檔
[ ] 像寸合用
[ ] 僅碼變時重構速（層快行）

忌

缺系依：R 含編碼之包需 -dev 庫。察 install.packages() 誤訊
層快失效：諸檔於裝包前複→碼每變必失快。先複鎖檔
大像：apt-get install 後 rm -rf /var/lib/apt/lists/*。考多段構
時區問：加 ENV TZ=UTC 或裝 tzdata 為時區覺操
行為 root：產加非 root 用：RUN useradd -m appuser && USER appuser

例

bash

# 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

參

setup-docker-compose - 調多容器
containerize-mcp-server - MCP R 服專
optimize-docker-build-cache - 進快策
manage-renv-dependencies - renv.lock 入 Docker 構
