39 |
40 | "Derivative Works" shall mean any work, whether in Source or Object
41 | form, that is based on (or derived from) the Work and for which the

44 | of this License, Derivative Works shall not include works that remain

67 | this License, each Contributor hereby grants to You a perpetual,
68 | worldwide, non-exclusive, no-charge, royalty-free, irrevocable
69 | copyright license to reproduce, prepare Derivative Works of,
70 | publicly display, publicly perform, sublicense, and distribute the
71 | Work and such Derivative Works in Source or Object form.
72 |
73 | 3. Grant of Patent License. Subject to the terms and conditions of
74 | this License, each Contributor hereby grants to You a perpetual,
75 | worldwide, non-exclusive, no-charge, royalty-free, irrevocable
76 | (except as stated in this section) patent license to make, have made,

82 | institute patent litigation against any entity (including a
83 | cross-claim or counterclaim in a lawsuit) alleging that the Work
84 | or a Contribution incorporated within the Work constitutes direct
85 | or contributory patent infringement, then any patent licenses
86 | granted to You under this License for that Work shall terminate
87 | as of the date such litigation is filed.
88 |
89 | 4. Redistribution. You may reproduce and distribute copies of the
90 | Work or Derivative Works thereof in any medium, with or without
91 | modifications, and in Source or Object form, provided that You
92 | meet the following conditions:
93 |
94 | (a) You must give any other recipients of the Work or
95 | Derivative Works a copy of this License; and
96 |
97 | (b) You must cause any modified files to carry prominent notices
98 | stating that You changed the files; and
99 |
100 | (c) You must retain, in the Source form of any Derivative Works
101 | that You distribute, all copyright, patent, trademark, and
102 | attribution notices from the Source form of the Work,

104 | the Derivative Works; and
105 |
106 | (d) If the Work includes a "NOTICE" text file as part of its
107 | distribution, then any Derivative Works that You distribute must
108 | include a readable copy of the attribution notices contained
109 | within such NOTICE file, excluding those notices that do not
110 | pertain to any part of the Derivative Works, in at least one
111 | of the following places: within a NOTICE text file distributed
112 | as part of the Derivative Works; within the Source form or
113 | documentation, if provided along with the Derivative Works; or,
114 | within a display generated by the Derivative Works, if and
115 | wherever such third-party notices normally appear. The contents
116 | of the NOTICE file are for informational purposes only and
117 | do not modify the License. You may add Your own attribution
118 | notices within Derivative Works that You distribute, alongside
119 | or as an addendum to the NOTICE text from the Work, provided
120 | that such additional attribution notices cannot be construed
121 | as modifying the License.
122 |
123 | You may add Your own copyright statement to Your modifications and
124 | may provide additional or different license terms and conditions
125 | for use, reproduction, or distribution of Your modifications, or

127 | reproduction, and distribution of the Work otherwise complies with
128 | the conditions stated in this License.
129 |
130 | 5. Submission of Contributions. Unless You explicitly state otherwise,
131 | any Contribution intentionally submitted for inclusion in the Work
132 | by You to the Licensor shall be under the terms and conditions of
133 | this License, without any additional terms or conditions.
134 | Notwithstanding the above, nothing herein shall supersede or modify
135 | the terms of any separate license agreement you may have executed
136 | with Licensor regarding such Contributions.
137 |
138 | 6. Trademarks. This License does not grant permission to use the trade
139 | names, trademarks, service marks, or product names of the Licensor,
140 | except as required for reasonable and customary use in describing the
141 | origin of the Work and reproducing the content of the NOTICE file.
142 |
143 | 7. Disclaimer of Warranty. Unless required by applicable law or
144 | agreed to in writing, Licensor provides the Work (and each
145 | Contributor provides its Contributions) on an "AS IS" BASIS,
146 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 | implied, including, without limitation, any warranties or conditions
148 | of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 | PARTICULAR PURPOSE. You are solely responsible for determining the
150 | appropriateness of using or redistributing the Work and assume any
151 | risks associated with Your exercise of permissions under this License.
152 |
153 | 8. Limitation of Liability. In no event and under no legal theory,
154 | whether in tort (including negligence), contract, or otherwise,
155 | unless required by applicable law (such as deliberate and grossly
156 | negligent acts) or agreed to in writing, shall any Contributor be
157 | liable to You for damages, including any direct, indirect, special,
158 | incidental, or consequential damages of any character arising as a
159 | result of this License or out of the use or inability to use the
160 | Work (including but not limited to damages for loss of goodwill,
161 | work stoppage, computer failure or malfunction, or any and all
162 | other commercial damages or losses), even if such Contributor
163 | has been advised of the possibility of such damages.
164 |
165 | 9. Accepting Warranty or Additional Liability. While redistributing
166 | the Work or Derivative Works thereof, You may choose to offer,
167 | and charge a fee for, acceptance of support, warranty, indemnity,
168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.
175 |
176 | END OF TERMS AND CONDITIONS

1 | # Using Kotlin in a Serverless Architecture with AWS Lambda
2 | Complete code per article for the complete series in medium https://medium.com/@juancho088/using-kotlin-in-a-serverless-architecture-with-aws-lambda-part-1-setting-up-the-project-87033790e2f4
3 |
4 | # First Steps
5 |
6 | 1. Install nodeJS (download [link](https://nodejs.org/en/download/))
7 | 2. Run the command `npm install -g serverless`
8 | 3. Create your project running the command `serverless create —-template aws-kotlin-jvm-gradle --path your_service`
9 | 4. To configure your AWS credentials execute `serverless config credentials --provider aws --key EXAMPLE --secret EXAMPLEKEY`
10 |
11 | # Package JSON
12 |
13 | 1. Create a package.json file with the minimum information so you can install serverless libraries.
14 | ```
15 | {
16 | "name": "my-blockbuster",
17 | "version": "1.0.0"
18 | }
19 | ```
20 |
21 | # Plugins
22 |
23 | ## Serverless to SAM Local
24 |
25 | You must have a functional Docker client on the system you plan to use SAM, so install that first if you don’t yet have it!
26 |
27 | ```
28 | npm install --save-dev serverless-sam
29 | ```
30 |
31 | Add the plugin in the serverless.yml file:
32 |
33 | ```
34 | plugins:
35 | - serverless-sam
36 | ```
37 |
38 | Compile your function using Shadow, that will generate a set of files in *build/libs/*:
39 |
40 | ````
41 | gradle build shadowJar
42 | ````
43 |
44 | Export and invoke your functions
45 |
46 | ```
47 | sls sam export -o template.yml
48 | sam local invoke hello <<< "{}"
49 | ```
50 |
51 | *Note:* You will always need to run this command every single time you want to test your lambda function.
52 | Also, by default the function names will start with capital letter.
53 |
54 | To invoke custom event.json files you can execute the next command:
55 |
56 | ```
57 | $ sam local invoke Hello -e src/main/resources/event.json
58 | ```
59 |
60 | *Note:* Serverless to SAM-local plugin has an error with the memory and timeout values (in general with most
61 | od the provider properties). To solve it, change the autogenerated template.yml to include the values
62 | that you defined in your serverless.yml file.
63 |
64 | ````
65 | MemorySize: 1024
66 | Timeout: 10
67 | ````
