For the next instructions to work, the following packages must be installed:<\/p>\n\n\n\n
- \n
docker<\/code><\/li>\n\n\n\nvim<\/code> (or any other text-editor)<\/li>\n<\/ul>\n\n\n\nInstall Portainer CE<\/h3>\n\n\n\n
First, let’s install Portainer!<\/p>\n\n\n\n
docker run -d -p 9000:9000 --name portainer --restart=always -v \/var\/run\/docker.sock:\/var\/run\/docker.sock -v portainer_data:\/data portainer\/portainer-ce:latest<\/code><\/pre>\n\n\n\nIt will download the latest portainer-ce<\/strong> image and run it on port 9000.<\/p>\n\n\n\n
Portainer CE is the Community Edition. It is the free and open source variant. Visit https:\/\/github.com\/portainer\/portainer<\/a> for the source code. Alternatively, there is the Business Edition<\/a>.<\/p>\n\n\n\n
Update Portainer<\/h3>\n\n\n\n
Next up: Let’s make it easier to update Portainer… in the future.<\/p>\n\n\n\n

Updating Portainer CE using a script<\/figcaption><\/figure>\n\n\n\n To simplify the update process, we will make two scripts.<\/p>\n\n\n\n
The first script will install<\/strong> Portainer. This script makes use of the same command we ran earlier. The second script will update<\/strong> Portainer and inherits the install script.<\/p>\n\n\n\n
#!\/bin\/sh\n\ndocker run -d -p 9000:9000 --name portainer \\\n--restart=always \\\n-v \/var\/run\/docker.sock:\/var\/run\/docker.sock \\\n-v portainer_data:\/data \\\nportainer\/portainer-ce:latest<\/code><\/pre>\n\n\n\nCall the above script
install_portainer.sh<\/code>. To make the file executable run:<\/p>\n\n\n\nchmod +x install_portainer.sh<\/code><\/pre>\n\n\n\nNow for the second script. To actually update a running container, we first need to stop<\/strong> and remove<\/strong> it.<\/p>\n\n\n\n
The data, such as login credentials, will not be removed. Those are stored in the volume
portainer_data<\/code>, as you can see in theinstall_portainer.sh<\/code> script.<\/p>\n\n\n\nWhen the container is removed we can pull<\/strong> the most up-to-date (latest) image, and install.<\/p>\n\n\n\n
After the new container is running we will remove all dangling images. This will ultimately remove the old image form the system. See the script below.<\/p>\n\n\n\n
#!\/bin\/sh\n\ndocker container stop portainer\ndocker container rm portainer\n\ndocker image pull portainer\/portainer-ce:latest\n\n.\/install_portainer.sh\n\ndocker image prune<\/code><\/pre>\n\n\n\nCall this script
update_portainer.sh<\/code>. Like the last script, use the following command to give it execution rights.<\/p>\n\n\n\nchmod +x update_portainer.sh<\/code><\/pre>\n\n\n\nTroubleshooting<\/h3>\n\n\n\n
When this is the first time using docker. It is possible that an error accuses along the lines of:<\/p>\n\n\n\n
Got permission denied while trying to connect to the Docker daemon socket at unix:\/\/\/var\/run\/docker.sock: Get http:\/\/%2Fvar%2Frun%2Fdocker.sock\/v1.39\/containers\/json: dial unix \/var\/run\/docker.sock: connect: permission denied<\/code><\/pre>\n\n\n\nIn that case the user does not have the correct permissions. To resolve this problem, add the user to the
docker<\/code> group.<\/p>\n\n\n\nusermod -aG docker $USER<\/code><\/pre>\n\n\n\nTo make the changes go into effect, log out and back in again.<\/p>\n\n\n\n
Docker compose<\/h2>\n\n\n\n
Alternatively, portainer can be installed using docker compose. Create a file called docker-compose.yml with the following content.<\/p>\n\n\n\n
services:\n portainer:\n container_name: portainer\n image: portainer\/portainer-ce:latest\n restart: always\n ports:\n - 9000:9000\n volumes:\n - \/var\/run\/docker.sock:\/var\/run\/docker.sock\n - portainer_data:\/data\n\nvolumes:\n portainer_data:<\/code><\/pre>\n\n\n\nNext, run
docker compose up -d<\/code>.<\/p>\n","protected":false},"excerpt":{"rendered":"Prerequisites This tutorial works for Linux systems.
