​
sudo semaphore user add --admin \
--login john \
--name=John \
--email=[email protected] \
--password=12345
​
sudo snap start semaphore
You can check the status of the Semaphore service using the following command:

After installation, you can set up Semaphore via Snap Configuration. Use the following command to see your Semaphore configuration:
sudo snap get semaphore
List of available options you can find in Configuration options reference.

Docker
Create a docker-compose.yml file with following content:
services:
  # uncomment this section and comment out the mysql section to use postgres instead of mysql
  #postgres:
    #restart: unless-stopped
    #image: postgres:14
    #hostname: postgres
    #volumes: 
    #  - semaphore-postgres:/var/lib/postgresql/data
    #environment:
    #  POSTGRES_USER: semaphore
    #  POSTGRES_PASSWORD: semaphore
    #  POSTGRES_DB: semaphore
  # if you wish to use postgres, comment the mysql service section below 
  mysql:
    restart: unless-stopped
    image: mysql:8.0
    hostname: mysql
    volumes:
      - semaphore-mysql:/var/lib/mysql
    environment:
      MYSQL_RANDOM_ROOT_PASSWORD: 'yes'
      MYSQL_DATABASE: semaphore
      MYSQL_USER: semaphore
      MYSQL_PASSWORD: semaphore
  semaphore:
    restart: unless-stopped
    ports:
      - 3000:3000
    image: semaphoreui/semaphore:latest
    environment:
      SEMAPHORE_DB_USER: semaphore
      SEMAPHORE_DB_PASS: semaphore
      SEMAPHORE_DB_HOST: mysql # for postgres, change to: postgres
      SEMAPHORE_DB_PORT: 3306 # change to 5432 for postgres
      SEMAPHORE_DB_DIALECT: mysql # for postgres, change to: postgres
      SEMAPHORE_DB: semaphore
      SEMAPHORE_PLAYBOOK_PATH: /tmp/semaphore/
      SEMAPHORE_ADMIN_PASSWORD: changeme
      SEMAPHORE_ADMIN_NAME: admin
      SEMAPHORE_ADMIN_EMAIL: admin@localhost
      SEMAPHORE_ADMIN: admin
      SEMAPHORE_ACCESS_KEY_ENCRYPTION: gs72mPntFATGJs9qK0pQ0rKtfidlexiMjYCH9gWKhTU=
      SEMAPHORE_LDAP_ACTIVATED: 'no' # if you wish to use ldap, set to: 'yes' 
      SEMAPHORE_LDAP_HOST: dc01.local.example.com
      SEMAPHORE_LDAP_PORT: '636'
      SEMAPHORE_LDAP_NEEDTLS: 'yes'
      SEMAPHORE_LDAP_DN_BIND: 'uid=bind_user,cn=users,cn=accounts,dc=local,dc=shiftsystems,dc=net'
      SEMAPHORE_LDAP_PASSWORD: 'ldap_bind_account_password'
      SEMAPHORE_LDAP_DN_SEARCH: 'dc=local,dc=example,dc=com'
      SEMAPHORE_LDAP_SEARCH_FILTER: "(\u0026(uid=%s)(memberOf=cn=ipausers,cn=groups,cn=accounts,dc=local,dc=example,dc=com))"
    depends_on:
      - mysql # for postgres, change to: postgres
volumes:
  semaphore-mysql: # to use postgres, switch to: semaphore-postgres
You must specify following confidential variables:
MYSQL_PASSWORD and SEMAPHORE_DB_PASS — password for the MySQL user.
SEMAPHORE_ADMIN_PASSWORD — password for the Semaphore's admin user.
SEMAPHORE_ACCESS_KEY_ENCRYPTION — key for encrypting access keys in database. It must be generated by using the following command: head -c32 /dev/urandom | base64.
Run the following command to start Semaphore with configured database (MySQL or Postgres):
docker-compose up
Semaphore will be available via the following URL http://localhost:3000.
For more information about the Docker Compose, see the Docker Compose reference.
Binary file
Python, Ansible and Git should be installed on your system.
Look into the manual installation on how to set-up your Python/Ansible/Systemd environment!
Download the *.tar.gz for your platform from Releases page. Unpack it and setup Semaphore using the following commands:
Linux (x64)
Linux (ARM64)
Windows (x64)
wget https://github.com/ansible-semaphore/semaphore/releases/\
download/v2.8.75/semaphore_2.8.75_linux_amd64.tar.gz
​
tar xf semaphore_2.8.75_linux_amd64.tar.gz
​
./semaphore setup
wget https://github.com/ansible-semaphore/semaphore/releases/\
download/v2.8.75/semaphore_2.8.75_linux_arm64.tar.gz
​
tar xf semaphore_2.8.75_linux_arm64.tar.gz
​
./semaphore setup
Invoke-WebRequest `
-Uri ("https://github.com/ansible-semaphore/semaphore/releases/" +
      "download/v2.8.75/semaphore_2.8.75_windows_amd64.zip") `
-OutFile semaphore.zip
​
Expand-Archive -Path semaphore.zip  -DestinationPath ./
​
./semaphore setup
Now you can run Semaphore:
./semaphore service --config=./config.json
Semaphore will be available via the following URL https://localhost:3000.
Run as a service
For more detailed information - look into the extended Systemd service documentation.
If you installed Semaphore via a package manager, or by downloading a binary file, you should create the Semaphore service manually.
Create the systemd service file:
Replace /path/to/semaphore and /path/to/config.json to your semaphore and config file path
sudo cat > /etc/systemd/system/semaphore.service <<EOF
[Unit]
Description=Semaphore Ansible
Documentation=https://github.com/ansible-semaphore/semaphore
Wants=network-online.target
After=network-online.target
​
[Service]
Type=simple
ExecReload=/bin/kill -HUP $MAINPID
ExecStart=/path/to/semaphore service --config=/path/to/config.json
SyslogIdentifier=semaphore

RestartSec=10s
​
[Install]
WantedBy=multi-user.target
EOF
Start the Semaphore service:
sudo systemctl daemon-reload
sudo systemctl start semaphore
Check the Semaphore service status:
sudo systemctl status semaphore
To make the Semaphore service auto start:
sudo systemctl enable semaphore
