Primarily setups a remote host with SSH to run Kontena with docker-compose.
Tested with: Ubuntu 16.04 Providers tested: AWS, DigitalOcean, Azure, OVH, packet.net, but should work with any provider (as it's just SSH and docker-compose)
Requires Ruby so bundle install first.
Make your host(s) accessible with SSH by having .ssh/config setup.
For example if you want to run locally on docker-machine:
Host myhost
HostName myhost.providercloud.com
User user
IdentityFile ~/.ssh/my_identity
Verify that ssh myhost works without a password.
bin/initialize deploys files required (using bin/deploy) to the target machine and runs initialization of master or node
# To use the defaults (:latest Kontena etc)
bin/initialize myhost master
# .. or to specify a version:
bin/initialize myhost master --kontena_version 1.1.4
# .. or to create a certificate automagically with Let's Encrypt SSL:
bin/initialize myhost master \
--kontena_version 1.1.4 \
--master_le_cert_hostname myhostname-that-points-to-the-public-ip-of-master.example.com \
--master_le_cert_email [email protected]
# .. for even more settings:
bin/initialize remote-host-in-ssh-config master --help
Master will boot and then logs will be shown -- hit ^C when the master has booted (will only disconnect from logs that can be seen with bin/logs remote-host-in-ssh-config master)
If you want to see more logs, use bin/logs remote-host-in-ssh-config master --help
Then you'll login to the master, add your user as the admin and create a grid:
# To use the defaults (creates a grid called kontenacompose with ETCD initial size 1)
bin/setup_master http(s?)://public_ip_or_hostname_of_the_master [email protected]
# .. or to specify settings:
bin/setup_master http(s?)://public_ip_or_hostname_of_the_master [email protected] \
--master_name mymaster \
--grid_name mygrid \
--grid_initial_size 3 \
--grid_token mybettertoken
# .. all settings
bin/setup_master --help
# To use the defaults (connects to master running in ws://localhost (one machine will be both master and node))
bin/initialize mynodehost node
# .. or to specify settings
bin/initialize mynodehost node \
--kontena_version 1.0.6 \
--master_uri ws(s?)://public_ip_or_hostname_of_the_master \
--grid_token mybettertoken
Hit ^C when the agent has connected and wait for the agent to join:
watch -n 1 kontena node ls
Test your grid:
kontena service create redis redis
kontena service scale redis 2
kontena service logs redis
To remove nodes (run docker-compose down) use:
bin/destroy mynodehost node
To remove master AND the entry for the master in Kontena Cloud use:
bin/destroy myhost master
Optionally to completely clean everything (containers and images) from Docker:
bin/destroy myhost docker
# ensure that you have the env locally
bin/cat_env myhostg master > kontena/master/env
# edit the version
bin/deploy myhostg master
bin/restart myhostg master
And the same for the node.
