apt-get 错误：找不到“docker-ce”的版本“5:19.03.4~3-0~ubuntu-bionic”

Question

文档 提供了安装特定版本的语法docker-ce：

$ sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io

---

在类似的行上，下面dockerfile使用上面的语法：

FROM jenkins/jenkins:lts

ENV DEBIAN_FRONTEND=noninteractive

ARG DOCKER_GID=497

# Create Docker Group with GID
# Set default value of 497 if DOCKER_GID set to blank string by Docker compose

                    make \
                    libssl-dev \
                    python3-pip

        docker-ce-cli=${DOCKER_VERSION:-5:19.03.4~3-0~ubuntu-bionic} \
        containerd.io && \
    usermod -aG docker jenkins

ARG DOCKER_COMPOSE=1.24.1

# Install docker compose
RUN curl -L "https://github.com/docker/compose/releases/download/${DOCKER_COMPOSE:-1.24.1}/docker-compose-$(uname -s)-$(uname -m)" \
    -o /usr/local/bin/docker-compose && \
    chmod +x /usr/local/bin/docker-compose

RUN pip3 install ansible boto3

# Change to jenkins user
USER jenkins

# Add jenkins plugin
COPY plugins.txt /usr/share/jenkins/plugins.txt
RUN /usr/local/bin/plugins.sh /usr/share/jenkins/plugins.txt

---

在下面一行失败（构建时）：

apt-get -y install docker-ce=${DOCKER_VERSION:-5:19.03.4~3-0~ubuntu-bionic} \
            docker-ce-cli=${DOCKER_VERSION:-5:19.03.4~3-0~ubuntu-bionic} \
            containerd.io && \

默认值是从命令检索的：apt-cache madison docker-ce | awk 'NR==1{print $3}'在我的本地 docker 主机中

---

其中docker-compose build给出以下错误：

apt-get -y install docker-ce docker-ce-cli containerd.io可以下载并安装最新版本的软件包，但为什么特定版本的软件包ubuntu下载并安装失败？ubuntu

apt-get -y install docker-ce=${DOCKER_VERSION:-5:19.03.4~3-0~ubuntu-bionic} \
                docker-ce-cli=${DOCKER_VERSION:-5:19.03.4~3-0~ubuntu-bionic} \
                containerd.io && \

Answer 1

您已根据构建主机上的可用内容选择了 Docker 版本，而不是根据正在构建的容器映像内的可用内容选择了 Docker 版本。jenkins:lts 映像基于 Debian Stretch，而不是 Ubuntu Bionic。

\n\n

Dockerfile 实际上只是运行相当普通的 Docker 操作。因此，例如，您可以运行docker run -ti -u root jenkins/jenkins:lts /bin/bash，手动运行 RUN 脚本，然后检查apt-cache容器内的输出：

\n\n

# apt-cache madison docker-ce\n docker-ce | 5:19.03.4~3-0~debian-stretch | https://download.docker.com/linux/debian stretch/stable amd64 Packages\n docker-ce | 5:19.03.3~3-0~debian-stretch | https://download.docker.com/linux/debian stretch/stable amd64 Packages\n docker-ce | 5:19.03.2~3-0~debian-stretch | https://download.docker.com/linux/debian stretch/stable amd64 Packages\n docker-ce | 5:19.03.1~3-0~debian-stretch | https://download.docker.com/linux/debian stretch/stable amd64 Packages\n docker-ce | 5:19.03.0~3-0~debian-stretch | https://download.docker.com/linux/debian stretch/stable amd64 Packages\n

\n\n

此外，失败的 docker 构建应该会留下部分完整的镜像；因此您可以直接使用它来调查故障。作为一个微不足道的失败步骤的例子RUN false：

\n\n

\xe2\x8b\xae\nRemoving intermediate container baaeab34bb8c\n ---> 6d34bab07796\nStep 3/3 : RUN false\n ---> Running in 8347f442dfaa\nThe command '/bin/sh -c false' returned a non-zero code: 1\n

\n\n

图像6d34bab07796留在周围。您可以将其传递给docker run并调查命令失败的原因。容器8347f442dfaa虽然已退出，但仍留在周围；docker container您也可以使用各种子命令来调查它。
