| # OpenSRP Deployment | ||
|
|
||
| ### Setting up an opensrp web instance | ||
|
|
||
| We support 3 deployment environments: stage, preview and production so one should first decide under which environment they want to set up the site in. | ||
|
|
||
| You also need to have the necessary SSH keys set up in your machine in order to gain access to the deployment server. Kindly refer to [this](https://github.com/onaio/infrastructure/blob/35172d3e0986d4f55749a780122326340b40e35a/docs/tools/ansible_playbooks.md) doc on how to generate and sign the SSH keys. | ||
|
|
||
| ### Adding inventories for a new web instance | ||
|
|
||
| To add inventories for an existing client, first clone the opensrp inventories repo [here](https://github.com/onaio/opensrp-inventories), then navigate to the host/client folder of choice. Also remember to clone the [playbooks](https://github.com/opensrp/playbooks/) repo in the same location as the opensrp inventories and follow the setup instructions as described [here](https://github.com/opensrp/playbooks#setup). | ||
|
|
||
| Each host has a stage, preview and production folder. Change dir into the environment folder of choice then create a `vars.yml` file with a set of variables used by the 4 ansible roles listed below that are used when running the playbook command: | ||
|
|
||
| - certbot - Installs certbot that is used to create website SSL certificates | ||
| - react - A role used to install react apps | ||
| - express - A role that installs and configures an express app | ||
| - nginx - Installs and configures Nginx | ||
|
|
||
| i.e if the client is `wellness-pass` and we want to deploy a staging site, we create the vars.yml file under `wellness-pass/stage/group_vars/web` directory. | ||
|
|
||
| Ansible roles usually offer a level of abstraction useful for organizing playbooks. | ||
|
|
||
| Below is a list of vars to be added in the host `vars.yml` file to be used by the above roles: | ||
|
|
||
| ``` | ||
| # General | ||

| ``` | ||
|
|
||
| You can also set up a `vault.yml` file where you can set sensitive values such as oauth secrets. To edit this file you should run the following command: | ||
| ` ansible-vault edit <client folder>/<environment>/group_vars/web/vault.yml --vault-password-file ~/opensrp/.vault_pass.txt` where the vault pass file is a file used with a password used to decrypt the vault.yml file. | ||
|
|
||
| After setting up the inventory we then add the client host or tag name under the `web` group var in the `hosts` file located at the root of each environment folder | ||
|
|
||
| ``` | ||
| [web:children] | ||
| <insert tag or client host name> | ||
| ``` | ||
|
|
||
| ### Deploying to stage | ||
|
|
||
| ``` | ||
| ansible-playbook -i opensrp-inventories/<client folder name>/staging/ web.yml --vault-password-file=~/opensrp/.vault_pass.txt -e react_git_version="v1.1.0" | ||
| ``` | ||
|
|
||
| ### Deploying to preview | ||
|
|
||
| ``` | ||
| ansible-playbook -i opensrp-inventories/<client folder name>/preview/ web.yml --vault-password-file=~/opensrp/.vault_pass.txt -e react_git_version="v1.1.0" | ||
| ``` | ||
|
|
||
| ### Deploying to production | ||
|
|
||
| ``` | ||
| ansible-playbook -i opensrp-inventories/<client folder name>/production/ web.yml --vault-password-file=~/opensrp/.vault_pass.txt -e react_git_version="v1.1.0" | ||
| ``` | ||
|
|
||
| If you have passed a default branch name to the `react_git_version` variable in the inventory of a particular host/client, you can deploy without having to provide the branch in the deploy command e.g | ||
|
|
||
| ``` | ||
| ansible-playbook -i opensrp-inventories/<client folder name>/production/ web.yml --vault-password-file=~/opensrp/.vault_pass.txt | ||
| ``` |
