SQL Server Docker Compose SQLCMD 不执行

Question

我目前正在尝试在 docker compose 中设置 SQL Server，并且想使用指令在构建时创建数据库RUN。这不起作用，但是当我使用 sh 在正在运行的容器上执行相同的命令时，它起作用

我的撰写文件如下所示：

version: "3.7"

services:
  mssql:
    build: ./mssql
    environment: 
      SA_PASSWORD: "Password12345!"
      ACCEPT_EULA: "Y"
    container_name: mssqlDB
    ports:
      - "1433:1433"
    restart: always

这是我的 Dockerfile：

FROM mcr.microsoft.com/mssql/server:2019-GA-ubuntu-16.04
COPY ./prod.sql /
RUN ./opt/mssql-bin/sqlcmd -S localhost -U SA -P "Password12345!" -Q "Create Database HelloWorld"
CMD ["/opt/mssql/bin/sqlservr"]

这是因为SQL Server实例尚未启动，您必须等待它。

从SQL Server 的 Docker Hub 官方页面，有一个 GitHub 存储库的链接，其中展示了如何在 Docker 容器上运行 sql 脚本。

下面我根据您的情况重新调整了 GitHub 代码

初始化.sh

# Typically SQL Server takes about 5-10 seconds to start up 
# Wait for the SQL Server to come up (90 sec) You can reduce to 20sec and see
sleep 90s

#run the setup script to create the DB and the schema in the DB
/opt/mssql-tools/bin/sqlcmd -S localhost -U sa -P password -d master -i prod.sql

入口点.sh

#start SQL Server, start the script to create the DB and import the data
/opt/mssql/bin/sqlservr & initialize.sh 

Dockerfile

FROM mcr.microsoft.com/mssql/server:2019-GA-ubuntu-16.04
COPY ./prod.sql /

# Grant permissions for the import-data script to be executable
RUN chmod +x ./initialize.sh

CMD /bin/bash ./entrypoint.sh

我个人制定的另一个解决方案是运行SQL Server服务并等待该服务启动。

创建.sh

FROM mcr.microsoft.com/mssql/server:2019-GA-ubuntu-16.04
COPY ./prod.sql /

# Grant permissions for the import-data script to be executable
RUN chmod +x ./initialize.sh

CMD /bin/bash ./entrypoint.sh

脚本.sql

CREATE TABLE MyTable (..)

Docker文件

FROM mcr.microsoft.com/mssql/server:2017-latest-ubuntu
EXPOSE 1433

WORKDIR /
COPY ./create.sh /src/
COPY ./script.sql /src/

ENV ACCEPT_EULA Y
ENV SA_PASSWORD P@ssw0rd

RUN echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bash_profile
RUN echo 'export PATH="$PATH:/opt/mssql-tools/bin"' >> ~/.bashrc

RUN ( /opt/mssql/bin/sqlservr --accept-eula & ) | grep -q "Service Broker manager has started" \
    && /src/create.sh P@ssw0rd \
    && pkill sqlservr
