About

This is OpenACS on Ubuntu base docker image (version 22.04) using s6-overlay. To install OpenACS I used code from Gustaf Neumann script install-oacs.sh. The base image is oupfiz5/openacs-s6.

OpenACS-S6 is self-hosting at https://chiselapp.com/user/oupfiz5/repository/openacs-s6.

If you are reading this on GitHub, then you are looking at a Git mirror of the self-hosting OpenACS-S6 repository. The purpose of that mirror is to test and exercise Fossil's ability to export a Git mirror and using GitHub CI/CD (GitHub Actions). Nobody much uses the GitHub mirror, except to verify that the mirror logic works. If you want to know more about OpenACS-S6, visit the official self-hosting site linked above.

All options have predifined values and store in .env file.

oacs_* variables

Setting these variables as environment variables with the "oacs_" prefix (suitable for e.g. docker setups for defaultConfig in NS_CONF (see naviserver commit). Code example from NaviServer configuration file is:

...
# All default variables in defaultConfig can be overloaded by
# 1) setting these variables in this file (highest precedence)
# 2) setting these variables as environment variables with
#    the "oacs_" prefix (suitable for e.g. docker setups)
# 3) set the variables from the default values.
#
set defaultConfig {
    hostname	localhost
    ipaddress	127.0.0.1
    httpport	8000
    httpsport	""

    server     "openacs"
    serverroot	/var/www/$server
    logroot	$serverroot/log/
    homedir	/usr/local/ns
    bindir	$homedir/bin
    db_name	$server
    db_user	$server
    db_host	localhost
    db_port	""
    db_password	"testing"
}
...

Environment variables from .env file are:

...
oacs_httpport='8000'
oacs_db_user="${PGUSER}"
oacs_db_passwod="${PGPASSWORD}"
oacs_db_name="${PGDATABASE}"
oacs_db_host="${PGHOST}"
oacs_db_port="${PGPORT}"
oacs_ipaddress='0.0.0.0'
...

OpenACS listen port

OACS_LISTEN_PORT set the http listen port for the openacs. In this case the OpenACS is accessible by URL http://localhost:8070.

OACS_LISTEN_PORT=8070 docker compose up

OpenACS docker image

Docker-compose uses the following variables for pulling OpenACS image from docker hub:

NaviServer configuration file

NS_CONF - configuration file. Default value is /usr/local/ns/conf/openacs-config.tcl

  1. Put the configuration file to rootfs/usr/local/ns/conf

  2. Run docker compose

    NS_CONF="/usr/local/ns/conf/my-config.tcl" docker-compose up

PostgreSQL docker image

Docker-compose uses the following variables for pulling postgres image from docker hub:

Database hostname

PGHOST set the database hostname for the openacs. By default it has name of docker-compose database service - postgres.

PGHOST=foo docker compose up

Database name

PGDATABASE set the database name for the openacs. By default it has name of docker-compose database service - openacs.

PGDATABASE=foo docker compose up

Database username

PGUSER set the database username for the openacs and postgres.

PGUSER=foouser docker compose up

Database password

PGPASSWORD set the database user password for the openacs and postgres.

PGPASSWORD=foopass docker compose up

Postgres tag

POSTGRES_TAG set the docker image tag for official postgres. Pay attention - some openacs version can use only correspond version of postgres.

POSTGRES_TAG="14.1-alpine" docker-compose up

Timezone

Set the timezone for the containers, defaults to UTC. To set the timezone set the desired timezone with the variable TZ. Useful for setup correct time in logging.

TZ="Europe/Moscow" docker compose up

CI/CD

For build and push docker images we use GitHub Actions workflow.

Maintenance

Shell access

For debugging and maintenance purposes you may want access the containers shell. If you are using Docker version 1.3.0 or higher you can access a running containers shell by starting bash using docker exec:

docker exec -it openacs-s6_openacs_1 /bin/bash

docker exec -it openacs-s6_postgres_1 /bin/bash
