|
(an example is provided in the Appendix below).
|
||||||
|
|
||||||
|
"Derivative Works" shall mean any work, whether in Source or Object
|
||||||
|
form, that is based on (or derived from) the Work and for which the
|
||||||
|
editorial revisions, annotations, elaborations, or other modifications
|
||||||
|
represent, as a whole, an original work of authorship. For the purposes
|
||||||
|
of this License, Derivative Works shall not include works that remain
|
||||||
|
separable from, or merely link (or bind by name) to the interfaces of,
|
||||||
|
the Work and Derivative Works thereof.
|
||||||
|
|
||||||
|
"Contribution" shall mean any work of authorship, including
|
||||||
|
the original version of the Work and any modifications or additions
|
||||||
|
to that Work or Derivative Works thereof, that is intentionally
|
||||||
|
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||||
|
or by an individual or Legal Entity authorized to submit on behalf of
|
||||||
|
the copyright owner. For the purposes of this definition, "submitted"
|
||||||

means any form of electronic, verbal, or written communication sent
|
||||||
|
to the Licensor or its representatives, including but not limited to
|
||||||

|
designated in writing by the copyright owner as "Not a Contribution."
|
||||||
|
|
||||||
|
"Contributor" shall mean Licensor and any individual or Legal Entity

||||||
|
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
copyright license to reproduce, prepare Derivative Works of,
|
||||||
|
publicly display, publicly perform, sublicense, and distribute the
|
||||||
|
Work and such Derivative Works in Source or Object form.
|
||||||
|
|
||||||
|
3. Grant of Patent License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
(except as stated in this section) patent license to make, have made,
|
||||||
|
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||||
|
where such license applies only to those patent claims licensable
|
||||||
|
by such Contributor that are necessarily infringed by their
|
||||||
|
Contribution(s) alone or by combination of their Contribution(s)
|
||||||
|
with the Work to which such Contribution(s) was submitted. If You
|
||||||
|
institute patent litigation against any entity (including a
|
||||||
|
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||||
|
or a Contribution incorporated within the Work constitutes direct
|
||||||
|
or contributory patent infringement, then any patent licenses
|
||||||
|
granted to You under this License for that Work shall terminate
|
||||||
|
as of the date such litigation is filed.
|
||||||
|
|
||||||
|
4. Redistribution. You may reproduce and distribute copies of the
|
||||||
|
Work or Derivative Works thereof in any medium, with or without
|
||||||
|
modifications, and in Source or Object form, provided that You
|
||||||
|
meet the following conditions:
|
||||||
|
|
||||||
|
(a) You must give any other recipients of the Work or
|
||||||
|
Derivative Works a copy of this License; and
|
||||||
|
|
||||||
|
(b) You must cause any modified files to carry prominent notices
|
||||||
|
stating that You changed the files; and
|
||||||
|
|
||||||
|
(c) You must retain, in the Source form of any Derivative Works
|
||||||
|
that You distribute, all copyright, patent, trademark, and
|
||||||
|
attribution notices from the Source form of the Work,
|
||||||
|
excluding those notices that do not pertain to any part of
|
||||||
|
the Derivative Works; and
|
||||||
|
|
||||||
|
(d) If the Work includes a "NOTICE" text file as part of its
|
||||||
|
distribution, then any Derivative Works that You distribute must
|
||||||
|
include a readable copy of the attribution notices contained
|
||||||
|
within such NOTICE file, excluding those notices that do not
|
||||||
|
pertain to any part of the Derivative Works, in at least one
|
||||||
|
of the following places: within a NOTICE text file distributed
|
||||||
|
as part of the Derivative Works; within the Source form or
|
||||||
|
documentation, if provided along with the Derivative Works; or,
|
||||||
|
within a display generated by the Derivative Works, if and
|
||||||
|
wherever such third-party notices normally appear. The contents
|
||||||
|
of the NOTICE file are for informational purposes only and
|
||||||
|
do not modify the License. You may add Your own attribution
|
||||||
|
notices within Derivative Works that You distribute, alongside
|
||||||
|
or as an addendum to the NOTICE text from the Work, provided
|
||||||
|
that such additional attribution notices cannot be construed
|
||||||
|
as modifying the License.
|
||||||
|
|
||||||
|
You may add Your own copyright statement to Your modifications and
|
||||||
|
may provide additional or different license terms and conditions
|
||||||
|
for use, reproduction, or distribution of Your modifications, or
|
||||||
|
for any such Derivative Works as a whole, provided Your use,
|
||||||
|
reproduction, and distribution of the Work otherwise complies with
|
||||||
|
the conditions stated in this License.
|
||||||
|
|
||||||
|
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||||
|
any Contribution intentionally submitted for inclusion in the Work
|
||||||
|
by You to the Licensor shall be under the terms and conditions of
|
||||||
|
this License, without any additional terms or conditions.
|
||||||
|
Notwithstanding the above, nothing herein shall supersede or modify
|
||||||
|
the terms of any separate license agreement you may have executed
|
||||||
|
with Licensor regarding such Contributions.
|
||||||
|
|
||||||
|
6. Trademarks. This License does not grant permission to use the trade
|
||||||
|
names, trademarks, service marks, or product names of the Licensor,
|
||||||
|
except as required for reasonable and customary use in describing the
|
||||||
|
origin of the Work and reproducing the content of the NOTICE file.
|
||||||
|
|
||||||
|
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||||
|
agreed to in writing, Licensor provides the Work (and each
|
||||||
|
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||||
|
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||||
|
implied, including, without limitation, any warranties or conditions
|
||||||
|
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||||
|
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||||
|
appropriateness of using or redistributing the Work and assume any
|
||||||
|
risks associated with Your exercise of permissions under this License.
|
||||||
|
|
||||||
|
8. Limitation of Liability. In no event and under no legal theory,
|
||||||
|
whether in tort (including negligence), contract, or otherwise,
|
||||||
|
unless required by applicable law (such as deliberate and grossly
|
||||||
|
negligent acts) or agreed to in writing, shall any Contributor be
|
||||||
|
liable to You for damages, including any direct, indirect, special,
|
||||||
|
incidental, or consequential damages of any character arising as a
|
||||||
|
result of this License or out of the use or inability to use the
|
||||||
|
Work (including but not limited to damages for loss of goodwill,
|
||||||
|
work stoppage, computer failure or malfunction, or any and all
|
||||||
|
other commercial damages or losses), even if such Contributor
|
||||||
|
has been advised of the possibility of such damages.
|
||||||
|
|
||||||
|
9. Accepting Warranty or Additional Liability. While redistributing
|
||||||
|
the Work or Derivative Works thereof, You may choose to offer,
|
||||||
|
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||||
|
or other liability obligations and/or rights consistent with this
|
||||||
|
License. However, in accepting such obligations, You may act only
|
||||||
|
on Your own behalf and on Your sole responsibility, not on behalf
|
||||||
|
of any other Contributor, and only if You agree to indemnify,
|
||||||
|
defend, and hold each Contributor harmless for any liability
|
||||||
|
incurred by, or claims asserted against, such Contributor by reason
|
||||||
|
of your accepting any such warranty or additional liability.

||||||
|
|
||||||

## <a id="3b878279a04dc47d60932cb294d96259"></a>Overview
|
||||||
|
|
||||||
|
This example automatically obtains and renews [Let's Encrypt](https://letsencrypt.org/) TLS certificates and sets up HTTPS in Nginx for multiple domain names using Docker Compose.
|
||||||
|
|
||||||
|
You can set up HTTPS in Nginx with Let's Encrypt TLS certificates for your domain names and get an A+ rating in [SSL Labs SSL Server Test](https://www.ssllabs.com/ssltest/) by changing a few configuration parameters of this example.
|
||||||
|
|
||||||
|
Let's Encrypt is a certificate authority that provides free X.509 certificates for TLS encryption.
|
||||||
|
The certificates are valid for 90 days and can be renewed. Both initial creation and renewal can be automated using [Certbot](https://certbot.eff.org/).
|
||||||
|
|
||||||
|
When using Kubernetes Let's Encrypt TLS certificates can be easily obtained and installed using [Cert Manager](https://cert-manager.io/).
|
||||||
|
For simple websites and applications, Kubernetes is too much overhead and Docker Compose is more suitable.
|
||||||
|
But for Docker Compose there is no such popular and robust tool for TLS certificate management.
|
||||||
|
|
||||||
|
The example supports separate TLS certificates for multiple domain names, e.g. `example.com`, `anotherdomain.net` etc.
|
||||||
|
For simplicity this example deals with the following domain names:
|
||||||
|
|
||||||
|
- `test1.evgeniy-khyst.com`
|
||||||
|
- `test2.evgeniy-khyst.com`
|
||||||
|
|
||||||
|
The idea is simple. There are 3 containers:
|
||||||
|
|
||||||
|
- **Nginx**
|
||||||
|
- **Certbot** - for obtaining and renewing certificates
|
||||||
|
- **Cron** - for triggering certificates renewal once a day
|
||||||
|
|
||||||
|
The sequence of actions:
|
||||||
|
|
||||||
|
1. Nginx generates self-signed "dummy" certificates to pass ACME challenge for obtaining Let's Encrypt certificates
|
||||||
|
2. Certbot waits for Nginx to become ready and obtains certificates
|
||||||
|
3. Cron triggers Certbot to try to renew certificates and Nginx to reload configuration daily
|
||||||

## <a id="1231369e1218613623e1b520c27ce190"></a>Initial setup
|
||||||
|
|
||||||
|
### <a id="ee68e5b99222bbc29a480fcb0d1d6ee2"></a>Prerequisites
|
||||||
|
|
||||||
|
1. [Docker](https://docs.docker.com/install/) and [Docker Compose](https://docs.docker.com/compose/install/) are installed
|
||||||
|
2. You have a domain name
|
||||||
|
3. You have a server with a publicly routable IP address
|
||||||
|
4. You have cloned this repository (or created and cloned a [fork](https://github.com/evgeniy-khist/letsencrypt-docker-compose/fork)):
|
||||||
|
```bash
|
||||||
|
git clone https://github.com/evgeniy-khist/letsencrypt-docker-compose.git
|
||||||
|
```
|
||||||
|
|
||||||
|
### <a id="288c0835566de0a785d19451eac904a0"></a>Step 0 - Create DNS records
|
||||||
|
|
||||||
|
For all domain names create DNS A records to point to a server where Docker containers will be running.
|
||||||
|
Also, consider creating CNAME records for the `www` subdomains.
|
||||||
|
|
||||||
|
**DNS records**
|
||||||
|
|
||||||
|
| Type | Hostname | Value |
|
||||||
|
| ----- | ----------------------------- | ---------------------------------------- |
|
||||||
|
| A | `test1.evgeniy-khyst.com` | directs to IP address `X.X.X.X` |
|
||||||
|
| A | `test2.evgeniy-khyst.com` | directs to IP address `X.X.X.X` |
|
||||||
|
| CNAME | `www.test1.evgeniy-khyst.com` | is an alias of `test1.evgeniy-khyst.com` |
|
||||||
|
| CNAME | `www.test2.evgeniy-khyst.com` | is an alias of `test2.evgeniy-khyst.com` |
|
||||||
|
|
||||||
|
### <a id="f24b6b41d1afb4cf65b765cf05a44ac1"></a>Step 1 - Edit domain names and emails in the configuration
|
||||||
|
|
||||||
|
Specify your domain names and contact emails for these domains with space as delimiter in the [`config.env`](config.env):
|
||||||
|
|
||||||
|
```bash
|
||||||
|
DOMAINS="test1.evgeniy-khyst.com test2.evgeniy-khyst.com"
|
||||||
|
CERTBOT_EMAILS="info@evgeniy-khyst.com info@evgeniy-khyst.com"
|
||||||
|
```
|
||||||
|
|
||||||
|
For two and more domains separated by space use double quotes (`"`) around the `DOMAINS` and `CERTBOT_EMAILS` variables.
|
||||||
|
|
||||||
|
For a single domain double quotes can be omitted:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
DOMAINS=test1.evgeniy-khyst.com
|
||||||
|
CERTBOT_EMAILS=info@evgeniy-khyst.com
|
||||||
|
```
|
||||||
|
|
||||||
|
### <a id="3414177b596079dbf39b1b7fa10234c6"></a>Step 2 - Configure Nginx virtual hosts
|
||||||
|
|
||||||
|
For each domain configure the Nginx [`server` block](https://nginx.org/en/docs/http/ngx_http_core_module.html#server) by updating `vhosts/${domain}.conf`:
|
||||||
|
|
||||||
|
- `vhosts/test1.evgeniy-khyst.com.conf`
|
||||||
|
- `vhosts/test2.evgeniy-khyst.com.conf`
|
||||||
|
|

```
|
||||||
|
|
||||||
|
Make sure `html/my-domain` directory (relative to the repository root) exists and countains the desired content and `html` directory is mounted as `/var/www/html` in `docker-compose.yml`:
|
||||||
|
|
||||||
|
```yaml

|
||||||
|
}
|

```
|
||||||
|
|
||||||
|
`my-backend` is the service name of your backend application in `docker-compose.yml`:
|
||||||
|
|
||||||
|
```yaml

### <a id="b56e2fee036d09a35898559d9889bae7"></a>Step 3 - Create named Docker volumes for dummy and Let's Encrypt TLS certificates
|
||||||
|
|
||||||
|
```bash
|
||||||
|
docker volume create --name=nginx_conf
|
||||||
|
docker volume create --name=letsencrypt_certs
|
||||||
|
```
|
||||||
|
|
||||||
|
### <a id="4952d0670f6fb00a0337d2251621508a"></a>Step 4 - Build images and start containers using staging Let's Encrypt server
|
||||||
|
|
||||||
|
```bash
|
||||||
|
docker compose up -d --build
|
||||||
|
docker compose logs -f
|
||||||
|
```
|
||||||
|
|
||||||
|
You can alternatively use the `docker-compose` binary.
|
||||||
|
|
||||||
|
For each domain wait for the following log messages:
|
||||||
|
|
||||||
|
```
|
||||||
|
Switching Nginx to use Let's Encrypt certificate
|
||||||
|

|
```
|
||||||
|
|
||||||
|
### <a id="46d3804a4859874ba8b6ced6013b9966"></a>Step 5 - verify HTTPS works with the staging certificates
|
||||||
|
|
||||||
|
For each domain open in browser `https://${domain}` and `https://www.${domain}` and verify that staging Let's Encrypt certificates are working:
|
||||||
|
|
||||||
|
- https://test1.evgeniy-khyst.com, https://www.test1.evgeniy-khyst.com
|
||||||
|
- https://test2.evgeniy-khyst.com, https://www.test2.evgeniy-khyst.com
|
||||||
|
|
||||||
|
Certificates issued by `(STAGING) Let's Encrypt` are considered not secure by browsers.
|
||||||
|
|
||||||
|
### <a id="04529d361bbd6586ebcf267da5f0dfd7"></a>Step 6 - Switch to production Let's Encrypt server
|
||||||
|
|
||||||
|
Stop the containers:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
docker compose down
|
||||||
|
```
|
||||||
|
|
||||||
|
Configure to use production Let's Encrypt server in [`config.env`](config.env):
|
||||||
|
|
||||||
|
```properties
|
||||||
|
CERTBOT_TEST_CERT=0
|
||||||
|
```
|
||||||
|
|
||||||
|
Re-create the volume for Let's Encrypt certificates:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
docker volume rm letsencrypt_certs
|
||||||
|
docker volume create --name=letsencrypt_certs
|
||||||
|
```
|
||||||
|
|
||||||
|
Start the containers:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
docker compose up -d
|
||||||
|
docker compose logs -f
|
||||||
|
```
|
||||||
|
|
||||||
|
### <a id="70d8ba04ba9117ff3ba72a9413131351"></a>Step 7 - verify HTTPS works with the production certificates
|
||||||
|
|
||||||
|
For each domain open in browser `https://${domain}` and `https://www.${domain}` and verify that production Let's Encrypt certificates are working.
|
||||||
|
|
||||||
|
Certificates issued by `Let's Encrypt` are considered secure by browsers.
|
||||||
|
|
||||||
|
Optionally check your domains with [SSL Labs SSL Server Test](https://www.ssllabs.com/ssltest/) and review the SSL Reports.
|
||||||

||||||
|
## <a id="45a36b34f024f33bed82349e9096051a"></a>Reloading Nginx configuration without downtime
|
||||||
|
|
||||||
|
Update a configuration in `vhosts/${domain}.conf`.
|
||||||
|
|
||||||
|
Do a hot reload of the Nginx configuration:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
docker compose exec --no-TTY nginx nginx -s reload
|
||||||
|
```
|
||||||
|
|
||||||
|
## <a id="35a7ab6c3c12c73a0fce287690b1c216"></a>Adding a new domain to a running solution
|
||||||
|
|
||||||
|
Let's add a third domain `test3.evgeniy-khyst.com` to a running solution.
|
||||||
|
|
||||||
|
### <a id="22e1d8b6115f1b1aaf65d61ee2557e52"></a>Step 0 - Create a new DNS records
|
||||||
|
|
||||||
|
Create DNS A record and CNAME record for `www` subdomain.
|
||||||
|
|
||||||
|
**DNS records**
|
||||||
|
|
||||||
|
| Type | Hostname | Value |
|
||||||
|
| ----- | ----------------------------- | ---------------------------------------- |
|
||||||
|
| A | `test3.evgeniy-khyst.com` | directs to IP address `X.X.X.X` |
|
||||||
|
| CNAME | `www.test3.evgeniy-khyst.com` | is an alias of `test3.evgeniy-khyst.com` |
|
||||||
|
|
||||||
|
### <a id="d0a4d4424e2e96c4dbe1a28dfddf7224"></a>Step 1 - Add domain name and email to the configuration
|
||||||
|
|
||||||
|
Add a new domain name (`test3.evgeniy-khyst.com`) and contact email to the [`config.env`](config.env):
|
||||||
|
|
||||||
|
```properties
|
||||||
|
DOMAINS="test1.evgeniy-khyst.com test2.evgeniy-khyst.com test3.evgeniy-khyst.com"
|
||||||
|
CERTBOT_EMAILS="info@evgeniy-khyst.com info@evgeniy-khyst.com info@evgeniy-khyst.com"
|
||||||
|
```
|
||||||
|
|
||||||
|
### <a id="96dc528b7365f5a119bb2b1893f60700"></a>Step 2 - Configure a new Nginx virtual hosts
|
||||||
|
|
||||||
|
Create a virtual host configuration file `vhosts/test3.evgeniy-khyst.com.conf` for the new domain.
|
||||||
|
|
||||||
|
For example, for serving static content use the following configuration:
|
||||||
|
|
||||||
|
```
|
||||||
|
location / {
|
||||||
|
root /var/www/html/test3.evgeniy-khyst.com;
|
||||||
|
index index.html index.htm;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Create a webroot `html/test3.evgeniy-khyst.com` and add static content.
|
||||||
|
|
||||||
|
### <a id="38f75935bf20b547d1f6788791645d5d"></a>Step 3 - Restart Docker containers
|
||||||
|
|
||||||
|
```bash
|
||||||
|
docker compose down
|
||||||
|
docker compose up -d
|

## <a id="bcd6f4d91c9b46c9af4d5b8c4a07db77"></a>Configuration file structure
|
||||||
|
|
||||||
|
To adapt the example to your domain names you need to change only [`config.env`](config.env):
|
||||||
|
|
||||||
|
```properties
|
||||||
|
DOMAINS="test1.evgeniy-khyst.com test2.evgeniy-khyst.com"
|
||||||
|
CERTBOT_EMAILS="info@evgeniy-khyst.com info@evgeniy-khyst.com"
|
||||||
|
CERTBOT_TEST_CERT=1
|
||||||
|
CERTBOT_RSA_KEY_SIZE=4096
|
||||||
|
```
|
||||||
|
|
||||||
|
Configuration parameters:
|
||||||
|
|
||||||
|
- `DOMAINS` - a space separated list of domains to manage certificates for
|
||||||
|
- `CERTBOT_EMAILS` - a space separated list of email for corresponding domains. If not specified, certificates will be obtained with `--register-unsafely-without-email`
|
||||||
|
- `CERTBOT_TEST_CERT` - use Let's Encrypt staging server (`--test-cert`)
|
||||||
|
|
||||||
|
Let's Encrypt has rate limits. So, while testing it's better to use staging server by setting `CERTBOT_TEST_CERT=1` (default value).
|
||||||
|
When you are ready to use production Let's Encrypt server, set `CERTBOT_TEST_CERT=0`.
