Question

这是我用于安装Postgres的Dockerfile。

# Set the base image to Ubuntu
FROM ubuntu:14.04

# Update the repository sources list
RUN apt-get update -y

################## BEGIN INSTALLATION ######################
# Install wget
RUN apt-get install wget -y

# Setup Postgres repository
RUN wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc 
| sudo apt-key add -

# Add Postgres repository
RUN sh -c "echo "deb http://apt.postgresql.org/pub/repos/apt/  trusty-pgdg main" >> /etc/apt/sources.list.d/postgresql.list"

# Update repository
RUN apt-get update -y

# Install Postgres with Postgis
RUN apt-get install postgresql-9.3-postgis-2.1 -y

如何为Postgres添加一个入口点，以便在Docker容器中自动启动Postgres

Answer 1

我自动启动Postgres的解决方案：

RUN chmod +x /etc/init.d/postgresql
CMD service postgresql start && tail -F /var/lib/postgresql/data/serverlog

Answer 2

您可以从官方docker-library/postgres Dockerfile获取想法：

ENTRYPOINT ["/docker-entrypoint.sh"]

EXPOSE 5432
CMD ["postgres"]

他们使用docker-entrypoint.sh脚本，最后会发布postgres

exec gosu postgres "$@"

Postgres的Docker入口点9.3
