Question

我通过pgadmins4从数据库中进行了备份，并存储到了我的dockerfile位置。

现在，我通过我的docker文件创建一个自定义docker映像：

FROM mdillon/postgis:11-alpine
LABEL MAINTAINER groot
ENV LANG en_US.utf8
ENV DBNAME pglocations
ENV USERNAME postgres

COPY init.sh /docker-entrypoint-initdb.d/
COPY ./pglocations.sql .

我建立了一个图像，当我想创建容器时，出现了这个错误：

server started

/usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/init.sh

在数据库中，我添加了 postgis 和 uuid.ossp 扩展名和2个功能。

通过Pgadmin4，我可以还原该数据库。

这是我的init.sh

#!/bin/sh
set -e

psql -v ON_ERROR_STOP=1 --dbname template1 --username postgres <<-EOSQL
    CREATE DATABASE "$DBNAME"
    WITH OWNER = postgres
    ENCODING = 'UTF8'
    LC_COLLATE = 'English_United States.1252'
    TABLESPACE = pg_default
    CONNECTION LIMIT = -1
    TEMPLATE template0;
EOSQL

#start postgres database
pg_restore -d "$DBNAME" pglocations.sql -c -U "$USERNAME"

这是我的容器挂壁处：

docker inspect -f'{{json .Mounts}}'pg-docker

[{"Type":"volume","Name":"a0334d571a61c0a17a23ca4be6a191143f39657967c52b3326abf8c011f54861","Source":"/var/lib/docker/volumes/a0334d571a61c0a17a23ca4be6a191143f39657967c52b3326abf8c011f54861/_data","Destination":"/var/lib/postgresql/data","Driver":"local","Mode":"","RW":true,"Propagation":""}]

首先遵循这些Steps

秒：您不应在/var/lib/postgresql/data阶段复制Build中的任何文件-将docker文件更改为：

FROM mdillon/postgis:11-alpine

LABEL MAINTAINER groot
ENV LANG en_US.utf8
ENV DBNAME pglocations
ENV USERNAME postgres
COPY init.sh /docker-entrypoint-initdb.d/

然后构建新图像后启动container：

docker run --name=pg-docker -p 5433:5432 -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=s123 -v  /path/to/pglocations.sql:/docker-entrypoint-initdb.d/pglocations.sql safapostgis:11.2

恢复pgadmin4在入口点docker容器中创建的数据库
