【问题描述】:
我想构建一个自定义 Postgres11 映像,其中创建了一些用户并安装了一些扩展。因为我希望在构建时创建这些,所以我不想使用docker-entrypoint-initdb.d。下一步也是恢复 sql 转储。
FROM postgres:11
ENV PG_MAJOR 11
ENV POSTGISV 2.5
ENV TZ Europe/Brussels
RUN apt-get update \
&& apt-get install -y --no-install-recommends \
postgresql-$PG_MAJOR-postgis-$POSTGISV \
postgresql-$PG_MAJOR-postgis-$POSTGISV-scripts
USER postgres
RUN initdb && pg_ctl -o "-c listen_addresses='*'" start &&\
psql -h 0.0.0.0 --command "CREATE USER docker WITH SUPERUSER PASSWORD 'docker';" &&\
psql -h 0.0.0.0 --command "CREATE USER akela_test WITH PASSWORD 'akela';" &&\
createdb -E UTF8 -U postgres -h 0.0.0.0 -O akela_test akela_test --template template0 &&\
psql -U postgres -d akela_test -h 0.0.0.0 -c 'CREATE EXTENSION IF NOT EXISTS "hstore";' &&\
psql -U postgres -d akela_test -h 0.0.0.0 -c 'CREATE EXTENSION IF NOT EXISTS "postgis";' &&\
psql -U postgres -d akela_test -h 0.0.0.0 -c 'CREATE EXTENSION IF NOT EXISTS "uuid-ossp";' &&\
psql -U postgres -d akela_test -h 0.0.0.0 -c "CREATE ROLE akela_db WITH LOGIN PASSWORD 'akela'" &&\
psql -U postgres -d akela_test -h 0.0.0.0 -c "GRANT ALL PRIVILEGES ON DATABASE akela_test to akela_db" &&\
psql -U postgres -d akela_test -h 0.0.0.0 -c "CREATE schema db" &&\
pg_ctl stop
# gunzip -c /tmp/dump.sql.gz | psql -U akela -h 0.0.0.0 akela
USER root
似乎有效:
...
CREATE SCHEMA
ALTER SCHEMA
CREATE ROLE
GRANT
CREATE SCHEMA
ALTER SCHEMA

运行图像但没有显示用户或数据库:
postgres=# \l

(3 rows)
postgres=# \du

可能是什么问题?
【问题讨论】:

为什么要在构建时创建用户?您的容器的入口点可能会重置或损坏数据库。您最好按照预期使用 initdb 创建用户
