###  No need to rebuild any docker images!
###
###  IMPORTANT:
###  ----------
###  When changing any values ensure to stop, rm and restart:
###  $ docker-compose stop

### Log to file or Docker logs.
###
### Logging to file means log files are available under log/

### Logging to Docker logs means log files are streamed to

###
### 1: Log to Docker logs
### 0: Log to file

###
### Relative or absolute path to the devilbox repository.
### (Used as a prefix for all mount paths)
### There is no need to change this.
###
### The only exception is for OSX users wanting to use NFS
### mounts instead of Filesystem mounts due to degraded performance
### on OSX.
###
### Note: When changing this variable you must re-create the container.
###       Simply remove it, it will be auto-created during the next start:
###
### $ docker-compose rm -f
###
DEVILBOX_PATH=.


###
### At what IP address should the docker services listen
### on the Host computer?
###
### The specified default should be fine for Linux and OSX (127.0.0.1:).
### If you are on windows, you will probably have to change
### it to the IP address of the docker machine.
###
### a.) Leave blank, to listen on all interfaces (no trailing colon ':')
###    LOCAL_LISTEN_ADDR=
### b.) If an IP is specified, note the trailing colon ':'
###    LOCAL_LISTEN_ADDR=127.0.0.1:
###
LOCAL_LISTEN_ADDR=


###
### This is the domain suffix your projects will be made available
### with mass-virtual-hosting.
### It is also required for the internal DNS server to be setup.
###
### Note: In addition to period or dot character ('.'), only ALPHA ([a-zA-Z]+) characters are supported.
###       Mac users should not use the .local TLD, as this will not resolve properly due Apple's
###       use of Multicast DNS.
###
### Note: If you use 'dvl.to' then there is no need for additional DNS as this always points
###       to 127.0.0.1 by default.
###
### Example:
###   TLD_SUFFIX=loc
### Makes your project available under <project>.loc
###
### Example:
###   TLD_SUFFIX=local
### Makes your project available under <project>.local
###
### Other domains which share same resolution to 127.0.0.1: ddev.site, dvl.to, 127-0-0-1.nip.io, lynxic.com..
###
TLD_SUFFIX=lvh.me


###
### Optional DNS configuration
### Allows you to add extra DNS records (above the wildcard entry)
### Useful if your host computer run other Docker services that you want to connect to or reach
### from within the Devilbox network by a custom hostname.
###
### Format:
### -------
### Resolve any custom defined hostname to an IP address (useable inside container and host os)
###     EXTRA_HOSTS=<hostname>=<ip>[,<hostname>=<ip>]
###
### Resolve any custom defined hostname to whatever IP address a CNAME resolves to
### (Useable inside the container and host OS).
### Note: CNAME must be resolvable by Google DNS
###     EXTRA_HOSTS=<hostname>=<CNAME>[,<hostname>=<CNAME>]
###
### Examples:
### ---------
### EXTRA_HOSTS=hostname.loc=1.2.3.4
### EXTRA_HOSTS=host.loc=1.2.3.4,host.example.org=3.4.5.6
EXTRA_HOSTS=


###
### Set your user id and group id
###
### This should be changed to the value of your local
### users uid and gid
###
### Type `id` on the terminal to find out your values
###
NEW_UID=1000
NEW_GID=1000


###
### Timezone for PHP Docker container (system and php.ini)
###
TIMEZONE=UTC

###
### TLD_SUFFIX domains are checked if they are set in the
### host computer /etc/hosts or available via attached DNS server.
### Timeout is done on vhosts.php (intranet) via ajax calls.
### In order to keep performance, set this to a low value.
### DNS checks might not succeed in time on slow machines.
### If DNS is valid, but timeout is expired, set this to a higher value.
###
### DNS_CHECK_TIMEOUT value is how many seconds to time out
### Default is to timeout after 1 second (DNS_CHECK_TIMEOUT=1)
###
DNS_CHECK_TIMEOUT=1

### Devilbox UI SSL Certificate generation
###
### When using SSL each certificate requires names for which it is responsible:
### Common Name as well as alternative names.
###
### Specify comma separated hostnames below by which you want to access the Devilbox.
### Those hostnames will be included in the SSL certificate for the Devilbox intranet.
### This has nothing to do for SSL certificates for projects, it is just for the intranet
### itself.
###
DEVILBOX_UI_SSL_CN=localhost,*.localhost,devilbox,*.devilbox,httpd


###
### Devilbox UI Password protection enable/disable (1/0)
###
### Set DEVILBOX_UI_PROTECT to 1 in order to password protect the
### intranet.
###
### Example:
###   DEVILBOX_UI_PROTECT=1
###   DEVILBOX_UI_PROTECT=0
###
DEVILBOX_UI_PROTECT=0


###
### Devilbox UI Password
###
### When DEVILBOX_UI_PROTECT=1, use the following password
### to log in. The password can always be changed.
### When changing the password, make sure to restart your
### PHP container.
###
### Example:
###   DEVILBOX_UI_PASSWORD=my-very-secure-password
###   DEVILBOX_UI_PASSWORD=Some pass with spaces
###
### The default username is 'devilbox'
###
DEVILBOX_UI_PASSWORD=password


###
### Enable the Devilbox Intranet?
###
### Example:
###   DEVILBOX_UI_ENABLE=1
###   DEVILBOX_UI_ENABLE=0
###
DEVILBOX_UI_ENABLE=1


###
### Automatically be logged in into phpMyAdmin
###
### Example:
###   DEVILBOX_VENDOR_PHPMYADMIN_AUTOLOGIN=1
###   DEVILBOX_VENDOR_PHPMYADMIN_AUTOLOGIN=0
###
DEVILBOX_VENDOR_PHPMYADMIN_AUTOLOGIN=1


###
### Automatically be logged in into phpPgAdmin
###
### Example:
###   DEVILBOX_VENDOR_PHPPGADMIN_AUTOLOGIN=1
###   DEVILBOX_VENDOR_PHPPGADMIN_AUTOLOGIN=0
###
DEVILBOX_VENDOR_PHPPGADMIN_AUTOLOGIN=1
