docker - 如何将php gd扩展名添加到Dockerfile

尝试使用Alpine进行部署时出现此错误:

phpoffice/phpspreadsheet 1.2.1 requires ext-gd * -> the requested PHP extension gd is missing from your system.

这是我的Dockerfile:

FROM php:7.2-alpine

RUN apk update
RUN apk add zlib-dev gd php7-gd
RUN docker-php-ext-install sockets pdo_mysql zip
RUN apk add --no-cache libpng libpng-dev && docker-php-ext-install gd

错误是 Jenkins 运行的输出。我认为这附近的某处失败了...

build:
    docker run --rm --tty --user $$(id -u):$$(id -g) \
        --volume "$$(pwd)":/app \
        --volume "$$(pwd)/ops/jenkins/github.token":/tmp/auth.json \
        --volume "$$(pwd)/ops/jenkins/composer_trust_github.com":/root/.ssh/config \
        composer install --no-dev
    rm -rf ops/docker/app.tar.gz
    tar -czvf ops/docker/app.tar.gz -X ops/jenkins/build_excludes .

docker run --rm --tty --user $(id -u):$(id -g) \
    --volume "$(pwd)":/app \
    --volume "$(pwd)/ops/jenkins/github.token":/tmp/auth.json \
    --volume "$(pwd)/ops/jenkins/composer_trust_github.com":/root/.ssh/config \
    --volume "$(pwd)/ops/jenkins/php/php.ini":/usr/local/etc/php/php.ini \
    composer install --no-dev

  Problem 1
    - Installation request for phpoffice/phpspreadsheet 1.2.1 -> satisfiable by phpoffice/phpspreadsheet[1.2.1].
    - phpoffice/phpspreadsheet 1.2.1 requires ext-gd * -> the requested PHP extension gd is missing from your system.

如何正确添加ext-gd？

更新:更多信息

Jenkins依次调用的Makefile命令如下:

prepare:
    git clone [email protected]:xxx/go-php-sqs-consumer
    cd go-php-sqs-consumer && glide install
    docker run --rm -v "${PWD}/go-php-sqs-consumer":/go/src/app -w /go/src/app golang:1.8.1-alpine go build -o consumer
    mv go-php-sqs-consumer/consumer ops/docker/consumer
    rm -rf go-php-sqs-consumer

build:
    echo "{\"github-oauth\":{\"github.com\":\"$$(credstash get github.tech-craft.jenkins-eu-west-1)\"}}" > ops/jenkins/github.token
    docker run --rm --tty --user $$(id -u):$$(id -g) \
        --volume "$$(pwd)":/app \
        --volume "$$(pwd)/ops/jenkins/github.token":/tmp/auth.json \
        --volume "$$(pwd)/ops/jenkins/composer_trust_github.com":/root/.ssh/config \
        composer install --no-dev
    rm -rf ops/docker/app.tar.gz
    ansible-vault decrypt config.*.json && chmod a+r config.*.json
    tar -czvf ops/docker/app.tar.gz -X ops/jenkins/build_excludes .

archive:
    aws s3api put-object --bucket craft-build --key "auth-api/${s3_key_version}.tar.gz" --body "ops/docker/app.tar.gz"
    aws s3api put-object --bucket craft-build --key "auth-api/current.tar.gz" --body "ops/docker/app.tar.gz"

containerise:
    cd ops/docker && docker build --pull --no-cache -t application-exporter-service .

最佳答案

这是我的操作方法，但是在php图像上，而不在alpine上。也许您可以对其进行“微调”以在 Alpine 上工作:

RUN apt-get update && \
    apt-get install -y libfreetype6-dev libjpeg62-turbo-dev libpng12-dev && \
    docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ && \
    docker-php-ext-install gd
