Postgres Database in Dockerfile - database

Question

I am trying to build a PostgreSQL image in DockerManually becuase I need to add some certain configuration for the database that doesnot exit in the postgres images provided with docker.
I wrote the following dockerfile
FROM alpine:3.7
#update the OS
RUN apk update
#installing alpine software kit
RUN apk add alpine-sdk
RUN apk update \
postgresql-$PG_MAJOR-postgis-$POSTGISV \
postgresql-$PG_MAJOR-postgis-$POSTGISV-scripts \
postgresql-$PG_MAJOR-pgrouting \
postgresql-$PG_MAJOR-pgrouting-scripts \
postgresql-server-dev-$PG_MAJOR
#installing postgresql
RUN apk add postgresql
RUN apk add openrc --no-cache
RUN apk update && apk upgrade
RUN apk add --no-cache --virtual .base_deps build-base openssl-dev zlib-dev libxml2-dev wget gnupg ca-certificates
RUN apk add --no-cache readline-dev glib-lang libssl1.0 postgresql postgresql-client
RUN apk add --update binutils
RUN apk add --no-cache sudo
RUN apk --purge del .base_deps
RUN echo "postgres ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/postgres
RUN chmod 600 /etc/sudoers.d/postgres
RUN sync
#RUN /etc/init.d/postgresql start
#RUN postgres -D /usr/local/pgsql/data
EXPOSE 5432
then I am trying to lunch the dockerfile with interactive shell with
docker run -it processID
then the follwoing command to instantite database
initdb Database
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locales
COLLATE: C
CTYPE: C.UTF-8
MESSAGES: C
MONETARY: C
NUMERIC: C
TIME: C
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".
Data page checksums are disabled.

You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
Success.
Then I am trying to lunch the database using the following command
postgres -D Database

2019-11-18 08:05:27.360 UTC [91] LOG: database system is shut down
I am getting some errors I do not know exactly why? any help would really be appreciated.
I did switch yo docker-compose, and here is an example of the file
version: "3"
services:
# Create a service named db.
db:
# Use the Docker Image postgres. This will pull the newest release.
image: "postgres:12.1-alpine"
# Give the container the name my_postgres. You can changes to something else.
container_name: "theNameOfDockerCompose"
# Setup the username, password, and database name. You can changes these values.
environment:
- POSTGRES_USER=DatabaseName
- POSTGRES_PASSWORD=Password
- POSTGRES_DB=development
# Maps port 54320 (localhost) to port 5432 on the container. You can change the ports to fix your needs.
ports:
- "5432:5432"
# Set a volume some that database is not lost after shutting down the container.
# I used the name postgres-data but you can changed it to something else.
volumes:
- ./postgres-data:/var/lib/postgresql/data
This is file is what I am using now.
But with Dockerfile, I still cannot enable the endpoints to access the dataBase.

update listen_addresses = '*' into postgresql/data/postgresql.conf

Answer 2

2019-11-18 08:05:27.360 UTC [91] FATAL: could not create lock file "/run/postgresql/.s.PGSQL.5432.lock": No such file or directory
points to a missing folder. Add
RUN mkdir -p /run/postgresql
to your Dockerfile
In addition, you need to change the listen_addresses = "*" in your postgresql/data/postgresql.conf. Otherwise, your database will be bound to localhost in your container and you will not be able to access it from anywhere except within that particular container. You can see that in your logs here
2019-11-18 08:05:27.358 UTC [91] LOG: listening on IPv4 address "127.0.0.1", port 5432
for the localhost binding. In addition, this will fix the following error message in your log
2019-11-18 08:05:27.358 UTC [91] LOG: could not bind IPv6 address "::1": Address not available
in which postgres failed to the bind for ipv6.
