Update the Devilbox

If you are in the initial install process, you can safely skip this section and come back once you actually want to update the Devilbox.

Update git repository

Stop container

Before updating your git branch or checking out a different tag or commit, make sure to properly stop all devilbox containers:

# Stop containers
host> cd path/to/devilbox
host> docker-compose stop

# Ensure containers are stopped
host> docker-compose ps

Case 1: Update master branch

If you simply want to update the master branch, do a git pull origin master:

# Update master branch
host> cd path/to/devilbox
host> git pull origin master

Case 2: Checkout release tag

If you want to checkout a specific release tag (such as 0.12.1), do a git checkout 0.12.1:

# Checkout release
host> cd path/to/devilbox
host> git checkout 0.12.1

Keep .env file in sync

Important

Whenever you check out a different version, make sure that your .env file is up-to-date with the bundled env-example file. Different Devilbox releases might require different settings to be available inside the .env file.

You can also compare your current .env file with the provided env-example file by using your favorite diff editor:

host> vimdiff .env env-example

host> diff .env env-example

host> meld .env env-example

Keep vhost-gen templates in sync

Important

Whenever you check out a different version, make sure that the vhost-gen templates that have been copied to any virtual hosts are up-to-date with the templates provided in templates/vhost-gen/.

Recreate container

Whenever the path of a volume changes (either due to upstream changes in git or due to you changing it manually in the .env file) you need to remove the stopped container and have them fully recreated during the next start.

# Remove anonymous volumes
host> cd path/to/devilbox
host> docker-compose rm

remove_stopped_container

Update Docker images

Updating the git branch shouldn't be needed to often, most changes are actually shipped via newer Docker images, so you should frequently update those.

This is usually achieved by issueing a docker pull command with the correct image name and image version or docker-compose pull for all currently selected images in .env file. For your convenience there is a shell script in the Devilbox git directory: update-docker.sh which will update all available Docker images at once for every version.

Note

The Devilbox own Docker images (Apache, Nginx, PHP and MySQL) are even built every night to ensure latest security patches and tool versions are applied.

Update one Docker image

Updating or pulling a single Docker image is accomplished by docker pull <image>:<tag>. This is not very handy as it is quite troublesome to do it separately per Docker image.

You first need to find out the image name and then also the currently used image tag.

host> grep 'image:' docker-compose.yml

image: cytopia/bind:0.11
image: devilbox/php-fpm:${PHP_SERVER:-7.0}-work
image: devilbox/${HTTPD_SERVER:-nginx-stable}:0.13
image: cytopia/${MYSQL_SERVER:-mariadb-10.1}:latest
image: postgres:${PGSQL_SERVER:-9.6}
image: redis:${REDIS_SERVER:-3.2}
image: memcached:${MEMCD_SERVER:-latest}
image: mongo:${MONGO_SERVER:-latest}

After having found the possible candidates, you will still have to find the corresponding value inside the ..env file. Let's do it for the PHP image:

host> grep '^PHP_SERVER' .env

PHP_SERVER=5.6

So now you can substitute the ${PHP_SERVER} variable from the first command with 5.6 and finally pull a newer version:

host> docker pull devilbox/php-fpm:5.6-work

Not very efficient.

Update all currently set Docker images

This approach is using docker-compose pull to update all images, but only for the versions that are actually set in .env.

host> docker-compose pull

Pulling bind (cytopia/bind:0.11)...
Pulling php (devilbox/php-fpm:5.6-work)...
Pulling httpd (devilbox/apache-2.2:0.13)...
Pulling mysql (cytopia/mysql-5.7:latest)...
Pulling pgsql (postgres:9.6)...
Pulling redis (redis:4.0)...
Pulling memcd (memcached:1.5.2)...
Pulling mongo (mongo:3.0)...

This is most likely the variant you want.

Update all available Docker images for all versions

In case you also want to pull/update every single of every available Devilbox image, you can use the provided shell script, which has all versions hardcoded and pulls them for you:

host> ./update-docker.sh

Checklist git repository

1. Ensure containers are stopped and removed/recreated (docker-compose stop && docker-compose rm)
2. Ensure desired branch, tag or commit is checked out or latest changes are pulled
3. Ensure .env file is in sync with env-example file
4. Ensure all of your custom applied vhost-gen templates are in sync with the default templates

Checklist Docker images

1. Ensure docker-compose pull or ./update-docker.sh is executed
