Installing on Ubuntu
I'm installing BOSH on an Ubuntu 16.04 LTS server vm running on top an ESXi 6.0u2 host.
BOSH v3 CLI
Start by updating your ubuntu vm.
~$ sudo apt update && sudo apt upgrade -y
Next lets install a few dependencies.
~$ sudo apt install -y build-essential zlibc zlib1g-dev ruby ruby-dev openssl libxslt-dev libxml2-dev libssl-dev libreadline6 libreadline6-dev libyaml-dev libsqlite3-dev sqlite3 git gnupg2 libcurl3
update: added libcurl3 to the dependency list as it was needed for bosh-deployment
Download the binary, make it executable, and move it to your path. Verify you have it installed.
~$ curl -Lo ./bosh https://s3.amazonaws.com/bosh-cli-artifacts/bosh-cli-3.0.1-linux-amd64 ~$ chmod +x ./bosh ~$ sudo mv ./bosh /usr/local/bin/bosh ~$ bosh -v version 3.0.1-712bfd7-2018-03-13T23:26:43Z Succeeded
BOSH Director
We are going to use the bosh-deployment tool and deploy bosh onto a vcenter environment.
~$ cd /opt/ ~$ sudo mkdir bosh-1 && cd bosh-1 ~$ sudo git clone https://github.com/cloudfoundry/bosh-deployment bosh-deployment
Now we need to install the director and specify our vcenter variables.
~$ bosh create-env bosh-deployment/bosh.yml \ --state=state.json \ --vars-store=creds.yml \ -o bosh-deployment/vsphere/cpi.yml \ -v director_name=bosh-1 \ -v internal_cidr=10.0.0.0/24 \ -v internal_gw=10.0.0.1 \ -v internal_ip=10.0.0.6 \ -v network_name="VM Network" \ -v vcenter_dc=my-dc \ -v vcenter_ds=datastore0 \ -v vcenter_ip=192.168.0.10 \ -v vcenter_user=root \ -v vcenter_password=vmware \ -v vcenter_templates=bosh-1-templates \ -v vcenter_vms=bosh-1-vms \ -v vcenter_disks=bosh-1-disks \ -v vcenter_cluster=cluster1
Of the variables you see above, the following are required and will not be automatically created:
- vcenter_dc
- this must match the name of your vcenter datacenter
- vcenter_ds
- this must match the name of your vcenter datastore or be a regex match.
- vcenter_ip
- The IP of your vcenter server. hostname is not specified as allowed in the BOSH documentation.
- vcenter_user
- username of account with admin rights.
- vcenter_password
- password for the above mentioned username
- vcenter_cluster
- name of the vcenter cluster that your hosts live in. This is required.
All other options listed above will work fine with the default values. If needed, they will be automatically created if not present.
SSH into BOSH Director
In order to SSH into the BOSH director, it needs to have been setup with a passwordless user during creation. This is generally defined through the jumpbox-user.yml
file during deployment. The below methods assume this was in place during deployment.
Manual
Search creds.yml
for the jumpbox private RSA key. Copy everything between -----BEGIN RSA PRIVATE KEY-----
and -----END RSA PRIVATE KEY-----
, including those (2) lines, into a new file called jumpbox.pub
.
Make sure that there are no spaces in front of any of the lines. I used the following to remove them:
~$ sed 's/ //g' jumpbox.pub
If the above looks right, then lets write it.
LINUX: ~$ sed -i 's/ //g' jumpbox.pub MAC: ~$ sed -i '' 's/ //g' jumpbox.pub
Next, set the correct permissions.
~$ sudo chmod 600 ./jumpbox.pub
Finally we should be able to ssh into our BOSH director
~$ ssh jumpbox@<director IP> -i <jumpbox rsa key> ex. ~$ ssh [email protected] -i ~/jumpbox.pub
The BOSH Way
Extract the RSA Key for the jumpbox user
~$ bosh int --path /jumpbox_ssh/private_key <path to creds.yml> ex. bosh int --path /jumpbox_ssh/private_key ~/Git/workspace/creds.yml
If that looks good, redirect to a file
~$ bosh int --path /jumpbox_ssh/private_key ~/Git/workspace/creds.yml > ~/jumpbox.pub
Finally we should be able to ssh into our BOSH director
~$ ssh jumpbox@<director IP> -i <jumpbox rsa key> ex. ~$ ssh [email protected] -i ~/jumpbox.pub
Basics
monit
Make sure you are root by either using sudo su -
or sudo -i
show running processes related to BOSH
~$ monit summary The Monit daemon 5.2.5 uptime: 23h 45m Process 'nats' running Process 'postgres' running Process 'blobstore_nginx' running Process 'director' running Process 'worker_1' running Process 'worker_2' running Process 'worker_3' running Process 'worker_4' running Process 'director_scheduler' running Process 'director_sync_dns' running Process 'director_nginx' running Process 'health_monitor' running Process 'warden_cpi' running Process 'garden' running Process 'uaa' running Process 'credhub' running System 'system_localhost' running
