# Centos 6 puppeteer docker image
2+
3+
docker image with [Google Puppeteer](https://github.com/GoogleChrome/puppeteer) installed for **Centos 6 only**
4+
5+
If you can, please use Centos 7 or higher but cause Centos 6 is EOL. Otherwise you can use this tool for Centos6.
6+
7+
Repo is based on [Google Puppeteer](https://github.com/GoogleChrome/puppeteer) and [alekzonder/docker-puppeteer] (https://github.com/alekzonder/docker-puppeteer)
8+
9+
## install
10+
11+
```
12+
docker pull gergokee/centos6-puppeteer:latest
13+
14+
```
15+
16+
## before usage
17+
18+
19+
1. You should **not** pass `--no-sandbox, --disable-setuid-sandbox` args when launching it, only if there is no other way, when you need to run it as **root** (which is not recommended).
20+
21+
```js
22+
const puppeteer = require('puppeteer');
23+
24+
(async () => {
25+
26+
console.info("Starting browser");
27+
28+
let browser;
29+
30+
try {
31+
32+
browser = await puppeteer.launch({});
33+
34+
} catch (e) {
35+
36+
console.info("Unable to launch browser mode in sandbox mode. Lauching Chrome without sandbox.");
37+
browser = await puppeteer.launch({args:[
38+
'--no-sandbox',
39+
'--disable-setuid-sandbox'
40+
]});
41+
42+
}
43+
44+
console.info("Browser successfully started");
45+
console.info("Closing browser");
46+
47+
await browser.close();
48+
49+
console.info("Done");
50+
51+
})();
52+
```
53+
54+
2. If you see errors like "ERR_NETWORK_CHANGED", write your script to check the output of it and make a loop till the output is not generating errors. Unfortunately the problem is that IPV6 needs to be turned off. And because latest docker for Centos 6 is docker v1.7, you are unable to pass the necessary flag: **--sysctl net.ipv6.conf.all.disable_ipv6=1**
55+
56+
57+
3. add `--enable-logging` for chrome debug logging http://www.chromium.org/for-testers/enable-logging
58+
59+
```js
60+
const puppeteer = require('puppeteer');
61+
62+
(async() => {
63+
64+
const browser = await puppeteer.launch({args: [
65+
'--no-sandbox',
66+
'--disable-setuid-sandbox',
67+
68+
// debug logging
69+
'--enable-logging', '--v=1'
70+
]});
71+
(async () => {
72+
73+
console.info("Starting browser");
74+
75+
let browser;
76+
77+
try {
78+
79+
browser = await puppeteer.launch({args: [
80+
'--enable-logging', '--v=1'
81+
]});
82+
83+
} catch (e) {
84+
85+
console.info("Unable to launch browser mode in sandbox mode. Lauching Chrome without sandbox.");
86+
browser = await puppeteer.launch({args:[
87+
'--no-sandbox',
88+
'--disable-setuid-sandbox',
89+
'--enable-logging', '--v=1'
90+
]});
91+
92+
}
93+
94+
console.info("Browser successfully started");
95+
console.info("Closing browser");
96+
97+
await browser.close();
98+
99+
console.info("Done");
100+
101+
})();
102+
103+
104+
```
105+
106+
## usage
107+
108+

109+

111+

112+
```
113+
114+
### custom script from dir
