APK Docker 无法锁定数据库：权限被拒绝

Question

我在 docker build

上有以下错误

错误：无法锁定数据库：权限被拒绝错误：无法打开 apk 数据库：权限被拒绝

奇怪的是 APK ADD 的第一部分工作正常：

Step 31/41 : RUN apk add --no-cache         bash         ca-certificates         openjdk11-jre-headless         tzdata
     tini         xmlstarlet     && wget -O  /usr/local/bin/wait-for-it.sh       "https://raw.githubusercontent.com/vishnubob/wait-for-it/a454892f3c2ebbc22bd15e446415b8fcb7c1cfa4/wait-for-it.sh" --no-check-certificate     && chmod +x /usr/local/bin/wait-for-it.sh

但第二部分没有：

Step 36/41 : RUN apk add openssh      && echo "root:Docker!" | chpasswd
 ---> Running in 5626e233c96d
ERROR: Unable to lock database: Permission denied

我的docker文件在下面

Answer 1

USER camunda
...
RUN apk add openssh

camunda 用户无法安装 apk 软件包，他没有这样做的权限。在切换用户之前安装所有包。或者稍后切换用户，就在设置 CMD 之前，具体取决于您要做什么。或者添加 sudo 并将 NOPASSWD awk 添加到 camunda 的 sudoers 文件中，然后使用 sudo 进行操作。无论哪种方式 - 确保您有权访问运行 apk 并关注 chpassw.
