⌘⌘ Limitations of Dockerfiles

The Dockerfile syntax and semantic does not allow for proper programming logic - see e.g. iterate in run command stackoverflow question

⌘⌘ Automating Mediawiki Installation

In 2015 we started with 1000 line bash script

profiwiki-install --help
./profiwiki-install.sh

options: 
       -c|--clean            : clean - clean up docker containers and volumes (juse with caution)
       -h|--help             : show this usage
       -i                    : use install.php to create LocalSettings.php
    -ismw SMW_VERSION        : install semanticmediawiki with the given version using composer
-composer|--composer         : install composer
       -l|--local            : local install (default is docker)
       -n|--needed           : check and install needed prequisites
       -m|--mysql            : initialize and start mysql
       -r|--random           : create random passwords
     -smw|--smw              : install Semantic MediaWiki

Here is an excerpt:

#
# get the passwords
# and save them in the given shell file
# paramams
#  1: l_pwconfig - the file for the password configuration
#
get_passwords() {
  local l_pwconfig="$1"
  if [ -f $l_pwconfig ]
  then
    # get the sysop password
    export SYSOP_PASSWD=$(cat $l_pwconfig  | grep SYSOP_PASSWD | cut -f2 -d'"')
    export MYSQL_PASSWORD=$(cat $l_pwconfig  | grep MYSQL_PASSWORD | cut -f2 -d'"')
  else
    if [ "$random_passwords" = "true" ]
    then
      # create a random SYSOP passsword
      export SYSOP_PASSWD=$(random_password)
      export MYSQL_PASSWORD=$(random_password)
    else
      password_dialog "ProfiWiki Setup" "Please specify passwords"
   fi
   local l_now=$(timestamp)
   cat << EOF > $l_pwconfig
#!/bin/bash
# generated by $0 at $l_now
export SYSOP_PASSWD="$SYSOP_PASSWD"
export MYSQL_PASSWORD="$MYSQL_PASSWORD"
EOF
  fi
