如何向Docker容器添加SSH访问权限

Question

我有以下文档文件

FROM alpine:3.10 as builder

ARG VERSION=7.12.0
ARG DISTRO=tomcat
ARG SNAPSHOT=true

ARG EE=false
ARG USER
ARG PASSWORD

RUN apk add --no-cache \
        ca-certificates \
        maven \
        tar \
        wget \
        xmlstarlet

COPY settings.xml download.sh camunda-tomcat.sh camunda-wildfly.sh  /tmp/

RUN /tmp/download.sh

#Enable Basic AUTH
COPY web.xml /camunda/webapps/engine-rest/WEB-INF/web.xml 

##### FINAL IMAGE #####

FROM alpine:3.10

ARG VERSION=7.12.0



ENV CAMUNDA_VERSION=${VERSION}
ENV DB_DRIVER=com.microsoft.sqlserver.jdbc.SQLServerDriver
ENV DB_URL=xx
ENV DB_USERNAME=dbname@xx
ENV DB_PASSWORD=xx
ENV DB_CONN_MAXACTIVE=20
ENV DB_CONN_MINIDLE=5
ENV DB_CONN_MAXIDLE=20
ENV DB_VALIDATE_ON_BORROW=true
ENV DB_VALIDATION_QUERY="SELECT 1"
ENV SKIP_DB_CONFIG=
ENV WAIT_FOR=
ENV WAIT_FOR_TIMEOUT=120
ENV TZ=UTC
ENV DEBUG=TRUE
ENV JAVA_OPTS="-Xmx768m -XX:MaxMetaspaceSize=256m"

EXPOSE 8080 8000

# Downgrading wait-for-it is necessary until this PR is merged
# https://github.com/vishnubob/wait-for-it/pull/68
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

RUN addgroup -g 1000 -S camunda && \
    adduser -u 1000 -S camunda -G camunda -h /camunda -s /bin/bash -D camunda
WORKDIR /camunda
USER camunda

#MSSQL SERVER JDBC DRIVER INSTALL
COPY mssql-jdbc-7.2.2.jre11.jar /camunda/lib/

ENTRYPOINT ["/sbin/tini", "--"]
CMD ["./camunda.sh"]

COPY --chown=camunda:camunda --from=builder /camunda .

这将运行带有外部SQL Paas数据库的CAMUNDA工作流引擎，并且运行良好。但是，为了进行故障排除，我需要能够通过SSH进入容器。

我在此网站上找到了如何做：https://docs.microsoft.com/en-us/azure/app-service/containers/tutorial-custom-docker-image

但是问题是ENTRYPOINT和CMD都只允许一个命令，所以我不确定如何启动SSH

# ssh
ENV SSH_PASSWD "root:Docker!"
RUN apt-get update \
        && apt-get install -y --no-install-recommends dialog \
        && apt-get update \
    && apt-get install -y --no-install-recommends openssh-server \
    && echo "$SSH_PASSWD" | chpasswd 

COPY sshd_config /etc/ssh/
COPY init.sh /usr/local/bin/
RUN chmod u+x /usr/local/bin/init.sh

EXPOSE 8000 2222

# end ssh config

以下是一些建议：

• 创建将在容器启动时运行的自定义脚本（CMD标记），以启动ssh守护程序和您的其他服务
• [（hacky）like in this answer只需将所有内容都放入CMD
