How can i add an Entrypoint for Postgres so that Postgres is automatically started in a Docker-container
My solution to start Postgres automatic:
RUN chmod +x /etc/init.d/postgresql
CMD service postgresql start && tail -F /var/lib/postgresql/data/serverlog
You can take ideas from the official docker-library/postgres Dockerfile:
ENTRYPOINT ["/docker-entrypoint.sh"]
EXPOSE 5432
CMD ["postgres"]
They use a docker-entrypoint.sh script which will, at the end, launch postgres
exec gosu postgres "$#"

Removing intermediate container 3d43e1d1cd96
---> 62f10ce67e07
Step 21/25 : RUN service mongodb start
---> Running in 42e08e7d7638
mongodb: unrecognized service
How do I start the service? I'm trying to start the service with the command: service mongodb start. Isn't that correct? And what does the line:
Removing intermediate container 3d43e1d1cd96
means?
Firstly, it should be service mongod start i guess. But this is not going to solve your problem.
While using Docker, your process has to be a foreground process service mongod start will go into background & your container will exit immediately.
You should use mongod foreground process as below -
CMD ["mongod"]
Put the above CMD at the end of Dockerfile to make sure your container runs mongod.
Official Dockerfile -
https://github.com/docker-library/mongo/blob/40056ae591c1caca88ffbec2a426e4da07e02d57/3.4/Dockerfile
If you want to run multiple processes, use docker ENTRYPOINT in conjunction with supervisord or use a wrapper script.
Ref - https://docs.docker.com/config/containers/multi-service_container/
So I'm having this problem where for some reason I can't install any package on my ubuntu system.
I'm currently on Ubuntu 16.10.
terminal install logs
Update:
I've done entered those commands and got this.
after update and apt-cache
What should I do now?
sudo apt-get install wget ca-certificates
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
sudo apt-get update
sudo apt-get install postgresql postgresql-contrib
After installing the PostgreSQL database server, by default, it creates a user ‘postgres’ with role ‘postgres’. Also creates a system account with the same name ‘postgres’. So to connect to Postgres server, log in to your system as user postgres and connect database.
sudo su - postgres
psql
First do
sudo apt-get update
You should get no errors upon updating. In case you do, then you might have issues with your firewall, or something blocking you from updating repositories. Check the output carefully.
And then search for the correct (exact!) package name using this command:
apt-cache search postgresql
As a last resort you could add external 3rd Party repository as described in this answer. Just remember to use your distribution name instead of "xenial".
It should work.
$ sudo apt-get install postgresql postgresql-client
If you are getting (E: Unable to locate package postgresql-12) while migrating following step may helps you:
sudo apt-get -y install bash-completion wget
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc |
sudo apt-key add -
sudo apt-get update
sudo apt-get -y install postgresql-12 postgresql-client-12
sudo systemctl status postgresql
ref:install postgres12 in ubuntu-18.04
Following Commands worked for me: sudo apt-get install wget ca-certificates
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ lsb_release -cs-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
sudo apt-get update
sudo apt install postgresql-11 libpq-dev
I'm trying to use the Dockerfile provided here and on building docker build . I get the error on line 69 (RUN createuser -s projop) which reports:
Step 15/27 : RUN /usr/bin/pg_ctl -D "/var/lib/pgsql/data" start
---> Using cache
---> ce049ebe4ff5
Step 16/27 : RUN sleep 60
---> Using cache
---> bf7bac638da6
Step 17/27 : RUN createuser -s projop # database user "projop" with admin rights
---> Running in 700e6e618060
createuser: could not connect to database postgres: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
My inital thought was the the postgres server had not had enough time to start up from the lines before so I extended the sleep command up to 60 seconds, but I still got this same error.
I also opened a bash session with a intermediate container after the sleep with docker run -it bf7bac638da6 bash. Within this bash session I tried to manually run the createuser -s projop line which gave the same error.
However, if I reran the command /usr/bin/pg_ctl -D "/var/lib/pgsql/data" start and then createuser -s projop it would work.
This is quite od as it seems the initial start command is not taking effect. Any ideas what might be happening here?

I've got a docker container, in which I'm installing mongo db. After installing,
I'm trying to start mongo and restore a mongo db dump. However, when I start the docker instance, I see that the user has been switched to root (as per supervisor instruction) but mongo is not started.
This is the supervisor snippet:
[supervisord]
nodaemon=true
[program:mongodb]
user=root
command=/usr/bin/mongod
This is my setup in the dockerfile:
RUN apt-get update && sudo apt-get install -y supervisor
RUN mkdir -p /var/log/supervisor
COPY supervisor.conf /etc/supervisor/conf.d/supervisor.conf
# Install MongoDB.
RUN \
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10 && \
echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen'
| tee /etc/apt/sources.list.d/mongodb.list && \
apt-get update && \
apt-get install -y mongodb-org && \
rm -rf /var/lib/apt/lists/*
# Define mountable directories.
VOLUME ["/data/db"]
# Define working directory.
WORKDIR /data
# Define default command.
CMD ["mongod"]
EXPOSE 27017
EXPOSE 28017
CMD ["/usr/bin/supervisord", "-c", "/etc/supervisor/supervisord.conf"]
Am I missing any configuration setting? Any help is appreciated.
You're not able to run mongodb because while installing mongodb some files need authentication, so you just have to replace apt-get install -y mongodb-org with apt-get install -y --no-authentication mongodb-org and you'll be able to install mongodb without any problem.
How can i enable the Postgis extension in a Dockerfile? The Postgres installation is already working
this is the command in Ubuntu:
sudo -u postgres psql -c "CREATE EXTENSION postgis;"
My Dockerfile:
# Set the base image to Ubuntu
FROM ubuntu:14.04
# Update the repository sources list
RUN apt-get update -y
################## BEGIN INSTALLATION ######################
# Postgres with Postgis
# Install wget
RUN apt-get install wget -y
# Setup Postgres repository
RUN wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
# Add Postgres repository
RUN sh -c "echo "deb http://apt.postgresql.org/pub/repos/apt/ trusty-pgdg main" >> /etc/apt/sources.list.d/postgresql.list"
# Update repository
RUN apt-get update -y
# Install Postgres with Postgis
RUN apt-get install postgresql-9.3-postgis-2.1 -y
# Change rights for start Postgresql
RUN chmod +x /etc/init.d/postgresql
# Start Postgresql
CMD service postgresql start && tail -F /var/lib/postgresql/data/serverlog
The solution for enable an extension
# Enable Postgis
RUN service postgresql start \
&& sudo -u postgres psql -c "CREATE EXTENSION postgis;"
RUN service postgresql stop
If you see other Dockerfiles using that psql -c command, like apache/marmotta Dockerfile, you will see lines like:
RUN service postgresql start \
&& psql --command "CREATE USER $DB_USER WITH PASSWORD '$DB_PASS';" \
&& psql --command "CREATE DATABASE $DB_NAME WITH OWNER $DB_USER;"
USER root
RUN service postgresql stop
In other words, you need to make sure the postgresql service is running for those commands to succeed.
