我试图让postgres 10.0在docker容器中工作.我有以下Dockerfile：
FROM postgres:10.0-alpine RUN apk add openrc --no-cache USER postgres RUN /etc/init.d/postgresql start RUN psql --command "IF NOT EXISTS (SELECT FROM pg_catalog.pg_user WHERE usename = 'user') THEN CREATE USER user WITH SUPERUSER ENCRYPTED PASSWORD 'password'; END IF;" RUN createdb main EXPOSE 5432 VOLUME ["/etc/postgresql","/var/log/postgresql","/var/lib/postgresql"] CMD ["/usr/lib/postgresql/10.0/bin/postgres","-D","/var/lib/postgresql/10.0/main","-c","config_file=/etc/postgresql/10.0/main/postgresql.conf"]
我收到以下错误：
/bin/sh: /etc/init.d/postgresql: not found
似乎/etc/init.d/postgresql确实缺失了.我究竟做错了什么？
解决方法
我完成了这个Dockerfile：
FROM postgres:10.0-alpine USER postgres RUN chmod 0700 /var/lib/postgresql/data &&\ initdb /var/lib/postgresql/data &&\ echo "host all all 0.0.0.0/0 md5" >> /var/lib/postgresql/data/pg_hba.conf &&\ echo "listen_addresses='*'" >> /var/lib/postgresql/data/postgresql.conf &&\ pg_ctl start &&\ psql -U postgres -tc "SELECT 1 FROM pg_database WHERE datname = 'main'" | grep -q 1 || psql -U postgres -c "CREATE DATABASE main" &&\ psql --command "ALTER USER postgres WITH ENCRYPTED PASSWORD 'mysecurepassword';" EXPOSE 5432
