Producing an Ubuntu Base Image for Swift 4 and Perfect 3

This guide will share steps that you can use to produce an Ubuntu Linux environment, which is suitable for use with the Swift 4 programming language, and with PerfectlySoft's Perfect 3 application framework.

Running as the Root User

Begin by installing, deploying, or otherwise utilizing an Ubuntu system. For ease of use, you may use the following command to perform the steps as the root user. You'll need to be using an administrative account, and you'll need its password. If you choose to skip this step, you'll need to prefix many of the steps in this guide with the sudo command.

sudo su

Running a Screen Session

If you are connected to the Ubuntu system via SSH, you might wish to establish a screen session for these steps in case you're disconnected. This section is not mandatory. You can skip to the next section of steps. To establish a screen session called "perfect," use:

screen -S perfect

If screen isn't installed, you'll need to install it:

apt-get install screen

To intentionally disconnect from a screen session, you can use Control-A, D. To reconnect to the intentionally disconnected screen session:

screen -r perfect

If you were unintentionally disconnected from your screen session, you might need to use:

screen -D -R perfect

Install Some Dependencies via APT

You can install the majority of dependencies for Swift 4 and for Perfect 3 via a free installation script Perfect Ubuntu

Install MongoDB from Source Code

Download the MongoDB source code:

cd /usr/src/
wget https://github.com/mongodb/mongo-c-driver/releases/download/1.3.5/mongo-c-driver-1.3.5.tar.gz

Decompress the MongoDB source code:

gunzip mongo-c-driver-1.3.5.tar.gz

Extract the MongoDB source code:

tar -xvf mongo-c-driver-1.3.5.tar

Remove the MongoDB source code archive:

rm mongo-c-driver-1.3.5.tar

Configure the MongoDB source code for compilation:

cd mongo-c-driver-1.3.5/
./configure --enable-sasl=yes

Compile MongoDB:

make

Install MongoDB:

make install

Finished

Congratulations! You now have an environment suitable for Swift 4 and Perfect 3.

Trying It Out

Now you can copy the Perfect 3 template project:

git clone https://github.com/PerfectlySoft/PerfectTemplate

Then build & run:

cd PerfectTemplate
swift run

You can test this application from a different shell with the curl command:

curl http://127.0.0.1:8181
