Setup a DevOps Work Machine¶

Enable Full Disk Encryption (FDE)¶

Important

Simply enabling encryption for your home directory is not enough.
If you already installed your OS and it doesn’t allow enabling FDE after installation, reinstall. No exceptions!
Remember that you need to type the selected passphrase on every boot. Select a reasonably-easy-to-type passphrase.

Example, enabling FDE on Ubuntu 22.04:

Select Advanced features….

Installation type screen of installer¶
Select LVM and enable encryption.

Advanced features screen of installer¶
Overwrite old OS

If you have used another OS on the machine without FDE enabled, select Overwrite empty disk space.

Choose a security key screen of installler¶

Set up SSH¶

Create a Key¶

ssh-keygen -t ed25519
cat ~/.ssh/id_ed25519.pub # copy key and paste in the next step

Distribute Key¶

Add key on https://git.tocco.ch (Your name (top right corner) → Settings → SSH Public Keys → Add Key …)

You also want to give the content of ~/.ssh/id_ed25519.pub to someone of operations. To that regard, you can post the public key in the Operations Public channel and ask for it to be granted access.

Tip

For admins: How to allow access is documented in Server Access (SSH/KVM/noVNC)

Setup Tocco Repository (Debian-Based Systems)¶

Public key: Tocco repo public key

Debian / Ubuntu¶

Hint

Currently supported distributions:

Debian bookworm / trixie
Ubuntu noble

Add repository and install tocco-metapackage:

curl https://docs.tocco.ch/_static/download/tocco-repo-keyring.asc | gpg --dearmor | sudo tee /usr/share/keyrings/tocco-repo-keyring.gpg >/dev/null
sudo tee <<<"deb [arch=amd64 signed-by=/usr/share/keyrings/tocco-repo-keyring.gpg] https://mirror.tocco.ch/repos/apt/tocco $(lsb_release -cs) main" /etc/apt/sources.list.d/tocco-repo.list >/dev/null
sudo apt update && sudo apt install -y tocco-metapackage

Set up Wireguard VPN¶

Note

macOS users use instructions in Set up Wireguard VPN (Mac Edition) instead.

Configure VPN¶

Install Wireguard:
```
apt install wireguard wireguard-tools
```

Generate private / public key pair:

(private=$(wg genkey); public=$(wg pubkey <<<$private); echo "private_key: $private; public_key: $public")

Submit the public_key to Operations Public channel and ask to be granted VPN access.

Make sure you keep the private_key, you’ll need it.
You’ll get a VPN config back. Replace the XXX placeholder in it with your private_key and then store it at /etc/wireguard/wg-tocco.conf.

Important

This is a per-device key. Generate a fresh key if you need access on an addational device. Using the same key on two devices will not work.

Tip

For admins: see Wireguard VPN.

Test VPN¶

Enable VPN:
```
wg-quick up wg-tocco
```

Test connection:

ping -A -c 3 10.148.60.1
ping -A -c 3 2001:8e3:5396:c9b::1
ping -A -c 3 tocco.ch

Disable VPN:
```
wg-quick down wg-tocco
```

Setup Git¶

Install Git¶

Debian-Based Systems¶

Already installed.

OSX Systems¶

If you are running OSX, you have git already installed. You can check the installed version using git -v.

If the installed version is not to your liking (or you are unable to update your OSX for some reason), you can create a separate git installation using brew and keep that on the version that you prefer. Brew will overwrite the linking of the git command for you, so that the brew version will be executed instead of the system version.

Configure Git¶

git config --global user.email "${USERNAME}@tocco.ch"  # replace ${USERNAME} with pgerber, …
git config --global user.name "${YOUR_NAME}"  # replace ${YOUR_NAME} with "Peter Gerber", …

Ignore some files in all repository by default:

Debian-Based Systems¶

mkdir -p ~/.config/git
cat >>~/.config/git/ignore <<EOF
.idea/
*~
.*.swp
EOF

OSX Systems¶

The first command creates a new global gitignore file and the second command tells your git to use this new file for global ignores.

touch ~/.gitignore_global
git config --global core.excludesfile ~/.gitignore_global
cat <<EOT >> ~/.gitignore_global
.DS_Store
.idea/
EOT

Configure SSH¶

Configure user name:

cat >>~/.ssh/config <<EOF
# First entry wins. So, override settings here, at the top.

Host *.tocco.cust.vshn.net
    User \${FIRST_NAME}.\${LAST_NAME}

# Comment in if you want to login as 'tadm' by default instead as 'tocco' (root permissions required).
# Host *.tocco.ch
#     User tadm
EOF

Replace ${FIRST_NAME}.${LAST_NAME} like this: peter.gerber.

Note

Non-Debian-based systems only (DragonFly BSD, Fedora Linux, FreeBSD, Hurd, Illumos, etc.):

Clone the tocco-dotfiles repository:
cd ~/src
git clone https://gitlab.com/toccoag/tocco-dotfiles.git
Link authorized_keys_tocco into SSH config directory:
mkdir -p ~/.ssh
ln -s ~/src/tocco-dotfiles/ssh/known_hosts_tocco ~/.ssh/
Adjust the path if your repository clone is located elsewhere.
Include config and set user name:
cat >>~/.ssh/config <<EOF
Host *
    Include ~/src/tocco-dotfiles/ssh/known_hosts_tocco
EOF

Setup IDEA¶

Install IDEA¶

Download the latest version and extract it:

cd ~/Download
wget https://download-cf.jetbrains.com/idea/ideaIC-XXXX.X.X.tar.gz
cd ~/install   # or wherever you want to install it
tar xf ~/Download/ideaIC-XXXX.X.X.tar.gz
ln -s ~/Download/ideaIC-XXXX.X.X idea
mkdir -p ~/bin
ln -s ~/install/idea/bin/idea.sh ~/bin/idea
rm ideaIC-XXXX.X.X.tar.gz

If an update is released that forces you to download a new *.tar.gz file, extract it and replace the link in ~/install/ using ln -sfn ideaIC-XXXX.X.X idea.

Hint

This assumes that ~/bin is in your $PATH which is the case on most Linux-based systems. If you had to create ~/bin, you may have to close and reopen the terminal for it to be added to $PATH.

If necessary, add it manually to $PATH by adding this to ~/.profile:

export PATH="$HOME/bin:$PATH"

Create Desktop Entry¶

open idea and find Tools → Create Desktop Entry… (or Configure → Create Desktop Entry… on the welcome screen).

Change default encoding for properties files¶

Open File → Settings → Editor → File Encodings and change Default encoding for properties files to UTF-8

Install Gerrit Plugin¶

Install Plugin under File → Settings → Plugins and search for Gerrit
Restart IDEA
Configure the plugin under File → Settings → Version Control → Gerrit
- Web-URL: https://git.tocco.ch
- Login: swuersten (your email address without @tocco.ch)
- Password: ******
- Enable “Push commits to Gerrit by default”

Disable creating run configuration automatically¶

Open File → Settings → Languages & Frameworks → Spring and disable Create run configuration automatically

Increase Memory Available to IDEA¶

Help → Edit Custom VM Options…
Say Yes to create a config file
Set max. memory (-Xmx) to something sensible (e.g. -Xmx3096m)

Increase Watch Limit (Linux only)¶

Create the file /etc/sysctl.d/50-idea.conf with the following content:

fs.inotify.max_user_watches=524288

Then load it with this command:

sysctl -p /etc/sysctl.d/50-idea.conf

Install Java¶

Required Java versions:

Java Version

Nice Versions

17

3.1 - 3.9

21

3.10 -

Debian-Based Systems¶

Use Eclipse Temurin builds provided Adoptium

Alternative sources:

Debian-only:

Most recent Java LTS version are usually available via backports:

cat >>/etc/apt/source.list.d/backports <<EOF
deb https://deb.debian.org/debian $(lsb_release -cs)-backports main
EOF

apt update

# install Java 11
apt install openjdk-11-jdk

Setup Gradle¶

There is no installation of gradle necessary as the gradle wrapper is used.

Repository Access¶

Create a file ~/.gradle/gradle.properties and copy the content from Bitwarden.

Increase Max. Number of Open Files¶

Create /etc/security/limits.d/open_file_limit.conf with this content:

*                -       nofile          1000000

Hint

Only effective once you logged out and in again.

Install Dependencies¶

On Ubuntu install the following dependencies:

apt install libjpeg62 libpng16-16

(there libraries are dynamically loaded by wkhtmltopdf)

On Ubuntu 22.04 and newer install the following dependencies. If there is a newer version released already, the version numbers in the command need to be adjusted.

wget http://nz2.archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2.23_amd64.deb
sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2.23_amd64.deb

This fixes the issue “cannot open shared object file: No such file or directory”.

On macOS add the gradle property wkhtmltopdfClassifier=osx to ~/.gradle/gradle.properties

Clone and Build Nice2¶

Download repository¶

Single command variant¶

Go to the repository page and use the command with the title Clone with commit-msg hook. It will create a folder nice2 in your current working directory, clone the repository into it, download the commit hook and make it runnable.

Manual variant¶

Tip

Only use this if the automatic variant above did not work for you.

mkdir ~/src
cd ~/src
git clone ssh://${USERNAME}@git.tocco.ch:29418/nice2  # replace ${USERNAME} with pgerber, …
cd nice2
scp -p -P 29418 ${USERNAME}@git.tocco.ch:hooks/commit-msg .git/hooks/  # replace ${USERNAME} with pgerber, …
git checkout ${BRANCH} # replace ${BRANCH} either with integration/master or integration/releases/${VERSION} where ${VERSION} is for example 2.29

Hint

Recent versions of scp have switched to sftp as underlying protocol. Gerrit does not currently support this protocol and you may see this error:

subsystem request failed on channel 0
scp: Connection closed

In such a case, enable the legacy protocol via -O flag:

scp -O -p -P 29418 ${USERNAME}@git.tocco.ch:hooks/commit-msg .git/hooks/  # replace ${USERNAME} with pgerber, …

Build nice¶

Test if Gradle build works:

cd ~/src/nice2
./gradlew build -x test

Create IDEA Project (Nice2 Integration)¶

open idea and find File → New → Project from Existing Sources… and follow the steps described below

select root directory of your nice2 clone (e.g. ~/tocco/src/nice2-2.25)
click OK
choose option Import project from external model → Gradle
click Finish
open new project either in a new window or in the existing window

Tip

It is recommended to create different git clone and idea project for each available version. For example one clone and project for master, one for v2.24, one for v2.25 and so on.

Hint

Note that there is already a run configuration for customer test ready to use (called “Start Nice2 (customer ‘test’)”).

If you need to run a different customer, just duplicate that run config and change the directory in the field Gradle project to your customer.

From version 3.5 on, the Nice instance gets a max memory of 1.2G (see -PjvmArgs=’-Xmx1200m’ in the run command in the run config). If this isn’t enough for your task at hand, you can increase the max memory by changing the number in the run config.

Caution

However, you shouldn’t carelessly increase the number if you’re running out of memory locally - it is probable that there’s something wrong, as 1.2G should be plenty enough to run any process within the Nice instance.

Setup OpenShift Client¶

Install Client¶

On Debian / Ubuntu this is already installed.

Tip

MacOs:

If you are running MacOS, just run brew install openshift-cli and ignore the rest of this chapter.

Install Docker (Optional)¶

Debian-based (e.g. Ubuntu):

apt install -y docker.io

Everyone else, find your OS here, follow the instructions, and hope for the best.

S3 Access Key¶

Ask operations (e.g. via Operations Public channel) to issue you an access key for our S3 storage. Once you retrieved the key, add it to ~/.aws/credentials like this:

[nice2]
aws_access_key_id=XXXXXXXXXXXXXXXXXXXX
aws_secret_access_key=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

The section must be called nice2, the name is hardcoded in Nice2.

Tip

For admins: how to issue a key is described in Create User.

S3 Access via `s3cmd` (Optional)¶

Install s3cmd:

apt install s3cmd

Configure s3cmd:

s3cmd --configure

Select the default for all options.

Adjust the following configuration entries in ~/.s3cfg:

[default]
access_key = XXXXXXXXXXXXXXXXXXXX
secret_key = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
host_base = objects.rma.cloudscale.ch
host_bucket = %(bucket)s.objects.rma.cloudscale.ch

The access and secret keys are the keys you obtained in the previous step.

Test access:

s3cmd info s3://tocco-nice-test >/dev/null
# no output expected

GitLab Account¶

Create a GitLab Account

You can create/reuse your personal account or create a Tocco-specific one. This is up to you.
Add your SSH key

Retrieve key: cat ~/.ssh/id_ed25519.pub
Enable 2FA

You can use an authenticator app like 2FAS / Aegis for this or a U2F device (if you own one).
Publish your username in the Slack channel public_operations and ask to be added to the group toccoag.

Setup Ansible¶

Hint

The following instruction have been tested on Debian / Ubuntu, for other operating systems make sure you have this installed:

Python3
Ansible >= 7.7

Various Python packages. See python3-* dependencies in tocco-metapackage’s CONTROL file for a up-to-date list.

Clone the repository:

mkdir -p ~/src
cd ~/src
# Access to group "toccoag" required
git clone git@gitlab.com:toccoag/ansible.git

Get Ansible Vault password(s)

Ansible Vault is used to store sensitive data (password, API keys) encrypted. You need a password to access them.

There is two Vaults:
1. One Vault that expects a file containing the password at ~/.ansible-password. This Vault is needed for server management and you generally only need it if you’re a part of the operations team.
2. The second Vault expects a file containing the password at ~/.ansible-tocco-password. This Vault is need to manage our application and is generally needed by devs and ops.
Ask one of your colleagues to get the Vault passwords and store in said files. Be sure to set proper permission on the files:
```
(umask 0077; echo ${PASSWORD_GOES_HERE} >~/.ansible-password)
(umask 0077; echo ${PASSWORD_GOES_HERE} >~/.ansible-tocco-password)
```

Setup Postgres¶

Install Postgres:
```
sudo apt install postgresql
```
Note

If you are running macOS, it is recommended that you install the multi-version app. This app allows you to run multiple postgres versions simultaneously and makes switching between versions easy. To install this app, browse to https://postgresapp.com/downloads.html and download the first installer under “Additional Releases” called “Postgres.app with all currently supported versions (Universal/Intel)”.
Setup Postgres for use with Ansible:
```
sudo apt install zstd
sudo -u postgres psql -c "CREATE ROLE \"$(id -un)\" WITH LOGIN SUPERUSER"
psql -c "CREATE DATABASE \"$(id -un)\"" postgres
```
The above is required to make sure Ansible can be used to copy databases. This creates a Postgres user with admin rights and with the same name as the Linux user. This allows to login via Unix socket without providing credentials.
Setup Postgres for local development

Initially create role and user:
```
CREATE ROLE nice_local WITH LOGIN SUPERUSER PASSWORD 'SET_YOUR_PASSWORD';
```
Add an application-development.properties file to the customer (path customer/NAME/src/main/resources):
```
hibernate.main.serverName=localhost
hibernate.main.user=nice_local
hibernate.main.password=SET_YOUR_PASSWORD
```
See Copy Database on how to copy a database to your local postgres server. If the database name is not the same as defined in application.properties also set hibernate.main.databaseName.

Setup tco (Optional)¶

Installed already on Debian / Ubuntu.

tco is a helper tool for anyone and contains many useful commands.

Tip

Other operating systems:

See the tco repository for installation instructions.

Setup Tocco Client (Optional)¶
