Install and configure Docker CE:
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo usermod -aG docker $(whoami)
docker login
If you prefer to perform these steps manually:
Note: MM-9791 introduced using docker-compose to manage containers. To preserve your data on upgrade, execute the following steps.
First, backup from any existing containers:
mysqldump -h 127.0.0.1 --column-statistics=0 -u mmuser -p mattermost_test > mm_mysql_backup.sql
pg_dump -U mmuser -W -d mattermost_test -h 127.0.0.1 > mm_postgres_backup.bak
Then after upgrading and starting the new docker-compose managed containers, restore the data:
mysql -u mmuser -p -h 127.0.0.1 mattermost_test < mm_mysql_backup.sql
psql -U mmuser -W -h 127.0.0.1 -f mm_postgres_backup.bak mattermost_test
If you don’t migrate your data, the new, docker-compose-managed containers will start out empty. To remove the old containers and destroy any existing data use make clean-old-docker.
Install docker-compose
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
Install Go (modify installation to latest Go version from https://golang.org/dl/):
sudo apt-get install -y build-essential
sudo rm -rf /usr/local/go
wget https://dl.google.com/go/go$VERSION.$OS-$ARCH.tar.gz
sudo tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz
Update your shell’s initialization script (e.g. .bashrc or .zshrc) and add the following:
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:/usr/local/go/bin
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
Log out and log back in to effect the changes above.
Clone the Mattermost source code from your fork:
git clone https://github.com/YOUR_GITHUB_USERNAME/mattermost-server.git
Start the server and test your environment:
cd 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 404 Not Found until the web app is configured. See Web App Developer Setup and Mobile App Developer Setup for additional setup.
The stop-server make target does not stop all the Docker containers started by run-server. To stop the running Docker containers:
make stop-docker
