# Asterisk in an Alpine Linux LXC container #

(January 2017)

Create the container:

	# lxc-create -n alpine-asterisk -t alpine -- -r v3.5
	# lxc-start -n alpine-asterisk
	# lxc-attach -n alpine-asterisk

Some general setup:

```
# cat << EOF > /root/.profile
# When using lxc-attach, do "su -" to trigger a login shell that runs .profile.
export PS1='--- \h \w \\$ '
export PAGER='less'
alias l='ls'
alias ll='ls -lah'
alias la='ls -a'
EOF
# apk update
# apk add tzdata s6
# cp /usr/share/zoneinfo/America/Detroit /etc/localtime
# echo 'America/Detroit' > /etc/timezone
# apk del tzdata
# rc-update add s6-svscan boot
```

Compile Asterisk:

	# wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-13-current.tar.gz
	# apk add build-base ncurses-dev util-linux-dev jansson-dev libxml2-dev sqlite sqlite-dev sqlite-libs bsd-compat-headers 
	# cd /src/asterisk-13.13.1/
	# ./configure
	# make menuselect

Add CORE-SOUNDS-EN-ULAW and CORE-SOUNDS-EN-G722 and MOH-OPSOUND-ULAW and MOH-OPSOUND-G722 and EXTRA-SOUNDS-EN-ULAW and EXTRA-SOUNDS-EN-G722. Then:

	# make
	# make install

## musl patch ##

If compilation fails with errors about GLOB_NOMAGIC and/or GLOB_BRACE in 'ael.flex', save the following as `asterisk-13.13.1/musl-glob-compat.patch`:
