Binary install without package manager
Install Calico binary on non-cluster hosts without a package manager.
Install Calico directly when a package manager isn’t available, or your provisioning system can easily handle copying binaries to hosts.
Before you begin…
- Ensure the Calico datastore is up and accessible from the host
- Ensure the host meets the minimum system requirements
- If you want to install Calico with networking (so that you can communicate with cluster workloads), you should choose the container install method
- Install and configure
This guide covers installing Felix, the Calico daemon that handles network policy.
Step 1: Download and extract the binary
This step requires Docker, but it can be run from any machine with Docker installed. It doesn’t have to be the host you will run it on (i.e your laptop is fine).
Use the following command to download the calico/node image.
docker pull calico/node:v3.16.1
Confirm that the image has loaded by typing
REPOSITORY TAG IMAGE ID CREATED SIZE calico/node v3.16.1 e07d59b0eb8a 2 minutes ago 42MB
Create a temporary calico/node container.
docker create --name container calico/node:v3.16.1
Copy the calico-node binary from the container to the local file system.
docker cp container:/bin/calico-node calico-node
Delete the temporary container.
docker rm container
Set the extracted binary file to be executable.
chmod +x calico-node
Step 2: Copy the
Copy the binary from Step 1 to the target machine, using any means (
ftp, USB stick, etc.).
Step 3: Create environment file
Use the following guidelines and sample file to define the environment variables for starting Calico on the host. For more help, see the Felix configuration reference.
For an etcdv3 datastore set the following
|FELIX_ETCDENDPOINTS||Comma separated list of etcdv3 cluster URLs, e.g. https://calico-datastore.example.com:2379|
|FELIX_ETCDCAFILE||Path to CA certificate to validate etcd’s server cert. Required if using TLS and not using a public CA.|
|Paths to certificate and keys used for client authentication to the etcd cluster, if enabled.|
For a Kubernetes datastore set the following
|KUBECONFIG||Path to kubeconfig file to access the Kubernetes API Server|
EnvironmentFile - save to
FELIX_DATASTORETYPE=etcdv3 FELIX_ETCDENDPOINTS=https://calico-datastore.example.com:2379 FELIX_ETCDCAFILE="/pki/ca.pem" FELIX_ETCDCERTFILE="/pki/client-cert.pem" FELIX_ETCDKEYFILE="/pki/client-key.pem"
Step 4: Create a start-up script
Felix should be started at boot by your init system and the init system must be configured to restart Felix if it stops. Felix relies on that behavior for certain configuration changes.
If your distribution uses systemd, then you could use the following unit file:
[Unit] Description=Calico Felix agent After=syslog.target network.target [Service] User=root EnvironmentFile=/etc/calico/calico.env ExecStartPre=/usr/bin/mkdir -p /var/run/calico ExecStart=/usr/local/bin/calico-node -felix KillMode=process Restart=on-failure LimitNOFILE=32000 [Install] WantedBy=multi-user.target
Once you’ve configured Felix, start it up via your init system.
service calico-felix start
Step 5: Initialize the datastore
You should configure a
node resource for each
host running Felix. In this case, the database is initialized after
creating the first
node resource. For a deployment that does not include
the Calico/BGP integration, the specification of a node resource just
requires the name of the node; for most deployments this will be the same as the
calicoctl create -f - <<EOF - apiVersion: projectcalico.org/v3 kind: Node metadata: name: <node name or hostname> EOF
The Felix logs should transition from periodic notifications
that Felix is in the state
wait-for-ready to a stream of initialization
