I am attempting to Dockerize a rails app using a number of online tutorials. I've reached the point where I can successfully fire up a docker container using docker-compose up. But once after that point, I have trouble connecting to my database. The following is my docker-compose up output:

You can see there in the final outputs that I have tried a number of different user roles in my database.yml that I know exist (e.g. when I use the Postgres app I can successfully access by db using those roles). When I try to take a look at my running databases with psql <dbname> or psql -U user -d <dbname> -h localhost I get the following error.
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
Finally, here are potentially relevant files.

Any help here would be appreciated. Thanks for your time.
Your role does not exist. This is due to POSTGRES_USER not being set in your docker-compose.yml file. If you set that value and recreate the container it will be created. POSTGRES_USER needs to match the user in the database.yml file for rails.

What is the easiest way to automatically transfer docker container files like this postgres database to the Windows 10 host?
Since docker contents are present in separate container and docker keeps its own file system , so you need to go inside the container to view docker container files.
For this you need to run the following command from command prompt :
docker exec -it <container-id> bash.
I have tried with same docker-compose.yml mentioned in your question and after running docker-compose up , this is the way I was able to view content of container files :
I'm trying to run the docker image kartoza/postgis locally on MacOS. It works perfectly when I run it on an Ubuntu instance on DigitalOcean, but when I try to interface with the local container using psql command line interface, I get the following:
Mac:~ User$ sudo psql -h localhost -U docker -p 5432 -l
psql: FATAL: role "docker" does not exist
Where docker is the username I specified when spinning up the container.
Below are the command I used to spin up the container, as well as the logs from the container:
Mac:~ User$ docker run --name "postgis" -p 5432:5432 -e ALLOW_IP_RANGE=0.0.0.0/0 -d -t kartoza/postgis

As far as I can see the user "docker" is the owner of the database "gis".
Can you set the database "gis":
psql -d gis -U username -h localhost
Then you can give your password.
If I run the redis:alpine Docker image using the commmand
docker run redis:alpine
I see several warnings:

1:M 08 May 08:29:32.311 * The server is now ready to accept connections on port 6379
I've tried to fix the first two of these warnings using the following Dockerfile:
FROM redis:alpine
COPY somaxconn /proc/sys/net/core/somaxconn
COPY sysctl.conf /etc/sysctl.conf
CMD ["redis-server", "--appendonly", "yes"]
where my local file somaxconn contains the single entry 511 and sysctl.conf contains the line vm.overcommit_memory = 1. However, I still get the same warnings when I build and run the container.
How can I get rid of these warnings? (There is mention of the issues in https://www.techandme.se/performance-tips-for-redis-cache-server/ but the solution described there, involving modifying rc.local, seems to pertain to Rasperry Pi).
Bad way to handle things: /proc is read-only filesystem to modify it you can run Docker in privileged mode than you can modify it after the container was started.
If running the container in privileged mode, you can disable THP using these commands:
# echo never > /sys/kernel/mm/transparent_hugepage/enabled
# echo never > /sys/kernel/mm/transparent_hugepage/defrag
Proper way: Ensure that you run newer versions of Docker (upgrade if needed). run subcommand has the --sysctl option:
$ docker run -ti --sysctl net.core.somaxconn=4096 --rm redis:alpine /bin/sh
root#9e850908ddb7:/# sysctl net.core.somaxconn
net.core.somaxconn = 4096
...
Unfortunately: vm.overcommit_memory is currently not allowed to be set via --sysctl paramter the same applies to THP (transparent_hugepage), this is because they are not namespaced. Thus to fix these warning in a container running on a Linux Host you can change them directly on host. Here the related Issues:
#19
#55
You don't need privileged mode for the proper way approach.
Following #ovanes response in this thread, I would complement that the proper way to fix it by running the container using Ansible playbook would be adding to the playbook the follow:
sysctls:
net.core.somaxconn: "4096"
Here is the ansible documentation about it and here a good explanation about this redis warning.
As for the overcommit_memory issue, it must be solved directly on the docker host, by adding vm.overcommit_memory = 1 in the /etc/sysctl.conf.
I would like use bitnami-docker-redmine with docker-compose persisting on Windows.
If i run the first exemple docker-compose.yml, without persisting application, redmine start and run perfectly.
But, i would like use this with persisting application exemple :

mariadb:

volumes:
- './mariadb:/bitnami/mariadb'
redmine:

ports:

volumes:
- './redmine:/bitnami/redmine'
And only MariaDB run, with error message :

My ./mariadb folder is good, but ./redmine is empty.
Do you have any idea why my persisting does not start completely ? Without the persisting, it works :(
docker-version : 1.13.0 (client/server)
plateform : Windows 10 (sorry, not test on Linux)
Thank you !
How do I set the server timezone in the MariaDB configuration?
The only thing I can find in the documentation is using command-line flags, which I don't want to do.
default_time_zone, which works on vanilla MySQL, isn't recognized by MariaDB.
It is default-time-zone (- instead of _):
[server]
default-time-zone=+00:00
Pasi had the right idea. 'UTC' didn't work but '+00:00' did.
Here is a complete summary collecting from above question and answers:
open
/etc/my.cnf.d/server.conf
change to example:
#
# These groups are read by MariaDB server.
# Use it for options that only the server (but not clients) should see
#
# See the examples of server my.cnf files in /usr/share/mysql/
#
# this is read by the standalone daemon and embedded servers
[server]
default-time-zone=-06:00
# this is only for the mysqld standalone daemon
[mysqld]
NOTE: for string
default-time-zone=-06:00 // this is equivalent to (america/edmonton)
You will need to figure out for your timezone to do so look up here https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
Restart the mysql server:
service mariadb restart
Testing:
[smith#home my.cnf.d]# mysql -u smith -p
Enter password:
