Developer Setup

1. Install and configure Docker CE: https://docs.docker.com/docker-for-mac/.

   Note: MM-9791 introduced using docker-compose to manage containers. To preserve your data on upgrade, execute the following steps.

   First, backup from any existing containers:

   mysqldump -h 127.0.0.1 --column-statistics=0 -u mmuser -p mattermost_test > mm_mysql_backup.sql
   pg_dump -U mmuser -W -d mattermost_test -h 127.0.0.1 > mm_postgres_backup.bak

   Then after upgrading and starting the new docker-compose managed containers, restore the data:

   mysql -u mmuser -p -h 127.0.0.1 mattermost_test < mm_mysql_backup.sql
   psql -U mmuser -W -h 127.0.0.1 -f mm_postgres_backup.bak mattermost_test

   If you don’t migrate your data, the new, docker-compose-managed containers will start out empty. To remove the old containers – destroying any existing data – use make clean-old-docker.

2. Download and install homebrew: https://brew.sh/.

3. Install Go:

   brew install go

4. Update your shell’s initialization script (e.g. .bashrc or .zshrc) and add the following:

   export GOPATH=$HOME/go
   export PATH=$PATH:$GOPATH/bin
   ulimit -n 8096

5. Re-source your shell’s initialization script to update GOPATH and PATH in your current shell:

   source $HOME/.bashrc

6. Fork https://github.com/mattermost/mattermost-server

7. Clone the Mattermost source code from your fork:

   export GITHUB_USERNAME=my_username
   mkdir -p $(go env GOPATH)/src/github.com/mattermost
   git clone https://github.com/$GITHUB_USERNAME/mattermost-server.git $(go env GOPATH)/src/github.com/mattermost/mattermost-server

8. Start the server:

   cd $(go env GOPATH)/src/github.com/mattermost/mattermost-server
   make run-server

   Note: If you see lot of nc: bad address 'elasticsearch' messages, eventually exiting with the message Service elasticsearch:9200 did not start within 300 seconds. Aborting..., increase the memory available for the Docker Engine by going to Docker’s preferences -> Advanced.

9. Test your environment:

   curl http://localhost:8065/api/v4/system/ping
   make stop-server

   If successful, the curl step will return a JSON object:

   {"AndroidLatestVersion":"","AndroidMinVersion":"","DesktopLatestVersion":"","DesktopMinVersion":"","IosLatestVersion":"","IosMinVersion":"","status":"OK"}

   Note: Browsing directly to http://localhost:8065/ will display a 404 Not Found until the web app is configured. See Web App Developer Setup and Mobile App Developer Setup for additional setup.

1. Install and configure Docker CE:

   curl -fsSL https://get.docker.com -o get-docker.sh
   sudo sh get-docker.sh
   sudo usermod -aG docker $(whoami)
   docker login

   If you prefer to perform these steps manually:

   • https://docs.docker.com/install/linux/docker-ce/ubuntu/
   • https://docs.docker.com/install/linux/linux-postinstall/

   Note: MM-9791 introduced using docker-compose to manage containers. To preserve your data on upgrade, execute the following steps.

   First, backup from any existing containers:

   mysqldump -h 127.0.0.1 --column-statistics=0 -u mmuser -p mattermost_test > mm_mysql_backup.sql
   pg_dump -U mmuser -W -d mattermost_test -h 127.0.0.1 > mm_postgres_backup.bak

   Then after upgrading and starting the new docker-compose managed containers, restore the data:

   mysql -u mmuser -p -h 127.0.0.1 mattermost_test < mm_mysql_backup.sql
   psql -U mmuser -W -h 127.0.0.1 -f mm_postgres_backup.bak mattermost_test

   If you don’t migrate your data, the new, docker-compose-managed containers will start out empty. To remove the old containers – destroying any existing data – use make clean-old-docker.

2. Install Go:

   sudo apt-get install -y build-essential
   wget https://storage.googleapis.com/golang/go1.12.linux-amd64.tar.gz
   sudo rm -rf /usr/local/go
   sudo tar -C /usr/local -xzf go1.12.linux-amd64.tar.gz

3. Update your shell’s initialization script (e.g. .bashrc or .zshrc) and add the following:

   export GOPATH=$HOME/go
   export PATH=$PATH:$GOPATH/bin
   export PATH=$PATH:/usr/local/go/bin

4. Edit /etc/security/limits.conf as an administrator (e.g. sudo) and add the following lines, replacing {username} with your username:

   {username}  soft  nofile  8096
   {username}  hard  nofile  8096

5. Logout and login to effect the changes above.

6. Fork https://github.com/mattermost/mattermost-server

7. Clone the Mattermost source code from your fork:

   export GITHUB_USERNAME=my_username
   mkdir -p $(go env GOPATH)/src/github.com/mattermost
   git clone https://github.com/$GITHUB_USERNAME/mattermost-server.git $(go env GOPATH)/src/github.com/mattermost/mattermost-server

8. Start the server and test your environment:

   cd $(go env GOPATH)/src/github.com/mattermost/mattermost-server
   make run-server
   curl http://localhost:8065/api/v4/system/ping
   make stop-server

   If successful, the curl step will return a JSON object:

   {"AndroidLatestVersion":"","AndroidMinVersion":"","DesktopLatestVersion":"","DesktopMinVersion":"","IosLatestVersion":"","IosMinVersion":"","status":"OK"}

   Note: Browsing directly to http://localhost:8065/ will display a 404 Not Found until the web app is configured. See Web App Developer Setup and Mobile App Developer Setup for additional setup.

1. Install and setup Docker.

   • If you are using Windows 10 Pro or Enterprise, you can use Docker for Windows: https://docs.docker.com/docker-for-windows/
   • For other Windows versions, or if you prefer to use VirtualBox, use Docker Toolbox: https://docs.docker.com/toolbox/toolbox_install_windows/

   Note: MM-9791 introduced using docker-compose to manage containers. To preserve your data on upgrade, execute the following steps.

   First, backup from any existing containers:

   mysqldump -h 127.0.0.1 --column-statistics=0 -u mmuser -p mattermost_test > mm_mysql_backup.sql
   pg_dump -U mmuser -W -d mattermost_test -h 127.0.0.1 > mm_postgres_backup.bak

This is an unofficial guide. Community testing, feedback and improvements are welcome and greatly appreciated.

1. Install the Windows Subsystem for Linux: https://docs.microsoft.com/en-us/windows/wsl/install-win10

2. Install and setup Docker:

   • Install Docker for Windows: https://docs.docker.com/docker-for-windows/
   • Link Windows Subsystem for Linux to Docker for Windows: https://medium.com/@sebagomez/installing-the-docker-client-on-ubuntus-windows-subsystem-for-linux-612b392a44c4.
     • You should end up with the Docker client running on Linux (WSL) sending commands to your Docker Engine daemon installed on Windows.

   Note: MM-9791 introduced using docker-compose to manage containers. To preserve your data on upgrade, execute the following steps.

   First, backup from any existing containers:

   mysqldump -h 127.0.0.1 --column-statistics=0 -u mmuser -p mattermost_test > mm_mysql_backup.sql
   pg_dump -U mmuser -W -d mattermost_test -h 127.0.0.1 > mm_postgres_backup.bak

   Then after upgrading and starting the new docker-compose managed containers, restore the data:

   psql -U mmuser -W -h 127.0.0.1 -f mm_postgres_backup.bak mattermost_test

   If you don’t migrate your data, the new, docker-compose-managed containers will start out empty. To remove the old containers – destroying any existing data – use make clean-old-docker.

3. Install Go (using bash):

   sudo apt-get install -y build-essential
   sudo rm -rf /usr/local/go
   wget https://storage.googleapis.com/golang/go1.12.linux-amd64.tar.gz
   sudo tar -C /usr/local -xzf go1.12.linux-amd64.tar.gz

4. Set up your Go workspace:

   1. In PowerShell mkdir d:\Projects\go
   2. In bash ln -s "/mnt/d/Projects/go" /home/<Linux User>/go

5. Update your shell’s initialization script (e.g. .bashrc or .zshrc) and add the following:

   export GOPATH=$HOME/go
   export PATH=$PATH:$GOPATH/bin
   export PATH=$PATH:/usr/local/go/bin
   ulimit -n 8096

6. Reload your bash configuration to effect the changes above:

   source ~/.bashrc

7. Fork Mattermost server on GitHub from https://github.com/mattermost/mattermost-server.

8. Clone the Mattermost source code from your fork:

   mkdir -p $(go env GOPATH)/src/github.com/mattermost
   git clone https://github.com/$GITHUB_USERNAME/mattermost-server.git $(go env GOPATH)/src/github.com/mattermost/mattermost-server

9. Start the server and test your environment:

   cd $(go env GOPATH)/src/github.com/mattermost/mattermost-server
   make run-server
   curl http://localhost:8065/api/v4/system/ping
   make stop-server

   If successful, the curl step will return a JSON object containing "status":"OK".

Troubleshooting: 

1. If you see an error like the input device is not a TTY. If you are using mintty, try prefixing the command with 'winpty'. Reinstall git for windows and make sure you choose Use Windows' default console window instead of Use MinTTY

2. The LDAP docker container is sometimes slow to start. If you see the following message, either increase the wait time in the make file or run make run twice in a row.

   Ldap test user test.one
   starting mattermost-openldap
   ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)
   ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)
