獲取鏡像：

docker pull mdillon/postgis

該 mdillon/postgis 鏡像提供了容器中運(yùn)行Postgres（內(nèi)置安裝PostGIS 2.5） 。該鏡像基于官方 postgres image，提供了多種變體，包括 Postgres 9 支持的 (9.4-9.6), Postgres 10和Postgres 11。

該鏡像保證由父 postgres image安裝了如下的擴(kuò)展：

• postgis
• postgis_topology
• fuzzystrmatch
• postgis_tiger_geocoder

除非 -e POSTGRES_DB 參數(shù)在啟動(dòng)時(shí)傳遞，該database將在admin用戶(hù)后被命名 (要么是 postgres 或是通過(guò) -e POSTGRES_USER指定)。 If you would prefer to use the older template database mechanism for enabling PostGIS, the image also provides a PostGIS-enabled template database called template_postgis.

Usage

In order to run a basic container capable of serving a PostGIS-enabled database, start a container as follows:

docker run --name some-postgis -e POSTGRES_PASSWORD=mysecretpassword -d mdillon/postgis

For more detailed instructions about how to start and control your Postgres container, see the documentation for the postgres image here.

Once you have started a database container, you can then connect to the database as follows:

docker run -it --link some-postgis:postgres --rm postgres \sh -c 'exec psql -h "$POSTGRES_PORT_5432_TCP_ADDR" -p "$POSTGRES_PORT_5432_TCP_PORT" -U postgres'

See the PostGIS documentation for more details on your options for creating and using a spatially-enabled database.

Known Issues / Errors

When You encouter errors due to PostGIS update OperationalError: could not access file "$libdir/postgis-X.X, run:

docker exec some-postgis update-postgis.sh

It will update to Your newest PostGIS. Update is idempotent, so it won't hurt when You run it more than once, You will get notification like:

Updating PostGIS extensions template_postgis to X.X.X NOTICE: version "X.X.X" of extension "postgis" is already installed NOTICE: version "X.X.X" of extension "postgis_topology" is already installed NOTICE: version "X.X.X" of extension "postgis_tiger_geocoder" is already installed ALTER EXTENSION Updating PostGIS extensions docker to X.X.X NOTICE: version "X.X.X" of extension "postgis" is already installed NOTICE: version "X.X.X" of extension "postgis_topology" is already installed NOTICE: version "X.X.X" of extension "postgis_tiger_geocoder" is already installed ALTER EXTENSION
